Test Block Diagram
Figure 2
shows the test setup for general testing of the TRF37T05.
2.2
Test Equipment
The following equipment is required for completing RF Testing:
•
Power supply with current readout — Agilent E3631 or equivalent
•
Signal generator for LO input signal — Agilent E4438C or equivalent
•
Arbitrary waveform generator — Agilent E4438C or equivalent
•
Spectrum analyzer — Agilent E4440A or equivalent
2.3
Calibration
The RF cables must be good quality RF cables due to the high-frequency signals.
•
Measure the insertion loss of the RF output cable, and use this value to compensate for the measured
output power.
•
Measure the insertion loss of the LO input cable, and use this value to compensate for the desired LO
power.
