Fig.7 Cross modulation measurement in band A.
V’meas =Vo × 15.4 dB (transformer ratio
= 5 and transformer loss).
Wanted output signal at fRFW = 180 MHz: Vow =104 dBV.
We measure the level of the unwanted signal Vou causing 0.3% AM modulation in the wanted output signal; fRFU = 185.5 MHz.
Vou =V’meas ×
+ 15.4 dB.
The cross modulation measurements are done at these frequencies:
- fRFW = 50.0 MHz; fRFU = 55.5 MHz; fosc = 88.9 MHz
- fRFW = 180.0 MHz; fRFU = 185.5 MHz; fosc = 218.9 MHz.
Filter characteristics: fc = 38.9 MHz, f3dBBW = 1.2 MHz, f30dBBW = 2.64 MHz.
