Tests as Run RFI-5G FE-Top SSV asRun 23/10/2023 Document Scope The objective of this document is to detail the procedures, results and conclusions to properly test at subsystem level the RFI-5G front-end top board. Several parts will be tested: Test of the LNA chain Test of the LO chain Test of the Front-End top board RF Test of the temperature sensor The as run versions of this document will have the title as "RFI-5G FE-Top SSV as run dd/mm/yyyy". Test of the LNA chain Test Description and Objectives The purpose of this test is to validate that the HMC342 LNA amplifier provides the expected +19 dB of gain for input signals between 24 to 25 GHz, and that the band-pass filter does not introduce more than the expected -4 dB of losses. Since the probing used is not the frequency range used, this is only a qualitative test to check if the LNA is providing gain and validate that the consumption is nominal. Requirements Verification This test does not verify any requirement, and is only to check that the board part works as expected. Test Set-Up The required components for this test are the following: RFI-5G front-end top board C.FL to SMA-2.92mm adapter C.FL cable RF probe SMA 50 Ohm RF load DC Block N to SMA adapter Power supply Signal Generator capable of at least 25 GHz Spectrum Analyzer capable of at least 25 GHz 2x Jumper cables 2x Banana cables 2x Crocodrile clips 2x SMA 2.92 mm cables SMA to SMP cable The steps to prepare the setup are the following: Connect the output from the signal generator to the antenna input of the RFI-5G front-end top board by using the C.FL cable and the C.FL to 2.92 mm adapter. Connect the power supply to the Vcc_LNA1 and GND pins with the jumper cables and the crocodile clips. Connect the DC-block N to SMA adapter to the spectrum analyzer input. Connect the RF probe to the spectrum analyzer using one SMA cable. Connect the SMA 50 Ohm RF load to the output of the mixer with the SMA to SMP cable. The diagram below represents the initial setup: Pass/Fail Criteria The test will be considered successful if the LNA shows to provide gain (~19 dB) and the power consumption matches the expected one (~43 mA at 3.3 V). There is though some margin accepted, since the RF probe and cables are not rated for the frequency range used.

Discussion in results y Test Results LNA: Perceived LNA gain is of ~16 dB. Compared to  the expected 19.2 dB of gain, the performance is considered valid, since the measuring technique introduces losses that are not accounted for. Additionally, the power consumption of 40 mA seems o be nominal since the expected was 43 mA. Band-pass filter: The band-pass filter seems to introduce ~4 dB of losses, which was expected from the specifications. Anomalies The signal power from the signal generator has been increased to 50 dBm because of the probing method used, otherwise the signal was not strong enough to be coupled to the probe and appear in the spectrum analyzer measurement. Conclusions This test concludes that the LNA chain implementation performs as expected. Test of the LO chain Test Description and Objectives The purpose of this test is to validate that the LO chain works as intended. This means that the HMC506 VCO provides a tone at the expected 8665.5 MHz, and that the HMC342 LO amplifier provides gain (~19 dB) so that the LO input of the mixer is over 12 dBm (~14 dBm). Since the probing used is not the frequency range used, this is only a qualitative test to check if the LO chain is providing the correct LO tone to the mixer and that the consumption is nominal. Requirements Verification This test does not verify any requirement, and is only to check that the board part works as expected. Test Set-Up The required components for this test are the following: RFI-5G front-end top board C.FL to SMA-2.92mm adapter C.FL cable RF probe SMA 50 Ohm RF load DC Block N to SMA adapter Power supply Spectrum Analyzer capable of at least 25 GHz 6x Jumper cables 6x Banana cables 6x Crocodrile clips 2x SMA 2.92 mm cables SMA to SMP cable The steps to prepare the setup are the following: Connect the output from the signal generator to the antenna input of the RFI-5G front-end top board by using the C.FL cable and the C.FL to 2.92 mm adapter. Connect the first channel of the  power supply to the Vcc_VCO and GND pins with the jumper cables and the crocodile clips. Connect the second channel of the power supply to the Vtune1 and GND pins with the jumper cables and the crocodile clips. Connect the third channel of the power supply to the Vcc_IF1Amp and GND pins with the jumper cables and the crocodile clips. Connect the DC-block N to SMA adapter to the spectrum analyzer input. Connect the RF probe to the spectrum analyzer using one SMA cable. Connect the SMA 50 Ohm RF load to the output of the mixer with the SMA to SMP cable. The diagram below represents the initial setup: Pass/Fail Criteria The test will be considered successful if the LO shows a tone at 8665.5 MHz +- 5%, if the LO amplifier provides the expected gain (~19 dB) and if the level of the LO input of the mixer is over 10 dBm. Additionally, the current consumption has to be nominal. Test Plan Step ID   Description Pass/Fail Criteria Actual Passed [Y/N] RFI-5G-TOP-LO-000 Make sure that the power supply is off.

Discussion in results y Test Results VCO: The VCO output provides a tone centered to a frequency provided by the Vtune voltage. In order to obtain the desired 8665.5 MHz of VCO frequency, the tuning voltage has been lowered from the expected 8.7 V to 8.17 V. Additionally, the frequency tuning appears to be erroneous: when the front-end is shifted or the cables are moved, the output of the VCO varies significantly. The power consumption of the VCO is of 81 mA at 3 V, which is higher than the expected 77 mA from the specification. The reasoning of this increase in consumption might be the bad connections used with the jumper. Frequency doubler and amplifier: The frequency doubler doubles the VCO output tone accordingly. The losses introduced by the doubling cannot be measured accurately. The LO amplifier provides a net gain of ~11 dB, and when considering the 50 Ohm resistor in series at its input to reduce the signal power that adds ~4dB of extra losses , the behavior of the amplifier is in pair with the LNA (is the same ic). The power consumption appears to be of a nominal 40 mA. Anomalies The list of anomalies is shown below: Erroneous VCO frequency tuning when front-end or cables are shifted. Higher power consumption than nominal of the VCO. The LO signal at the input of the mixer seems to be of not powerful enough to drive the mixer. Conclusions The VCO behavior is validated, but its characteristics need to be measured with the interface board attached, to reduce the impedance of the jumper cables used and improve the performance.

Test Readiness Review minutes and Post Test Review minutes Test of the LO chain Test Description and Objectives The purpose of this test is to validate that the LO chain works as intended. This means that the HMC506 VCO provides a tone at the expected 8665.5 MHz, and that the HMC342 LO amplifier provides gain (~19 dB) so that the LO input of the mixer is over 12 dBm (~14 dBm). Since the probing used is not the frequency range used, this is only a qualitative test to check if the LO chain is providing the correct LO tone to the mixer and that the consumption is nominal. Requirements Verification This test does not verify any requirement, and is only to check that the board part works as expected. Test Set-Up The required components for this test are the following: RFI-5G front-end top board C.FL to SMA-2.92mm adapter C.FL cable RF probe SMA 50 Ohm RF load DC Block N to SMA adapter Power supply Spectrum Analyzer capable of at least 25 GHz 6x Jumper cables 6x Banana cables 6x Crocodrile clips 2x SMA 2.92 mm cables SMA to SMP cable The steps to prepare the setup are the following: Connect the output from the signal generator to the antenna input of the RFI-5G front-end top board by using the C.FL cable and the C.FL to 2.92 mm adapter. Connect the first channel of the  power supply to the Vcc_VCO and GND pins with the jumper cables and the crocodile clips. Connect the second channel of the power supply to the Vtune1 and GND pins with the jumper cables and the crocodile clips.

Several parts will be tested: Test of the LNA chain Test of the LO chain Test of the Front-End top board RF Test of the temperature sensor The as run versions of this document will have the title as "RFI-5G FE-Top SSV as run dd/mm/yyyy". Test of the LNA chain Test Description and Objectives The purpose of this test is to validate that the HMC342 LNA amplifier provides the expected +19 dB of gain for input signals between 24 to 25 GHz, and that the band-pass filter does not introduce more than the expected -4 dB of losses.
