Receiver characteristics (RX-module alone) without filtering
   Receive RF-frequency
   Input/Output return loss
   Noise figure
   Receive IF-frequency
   Receiver gain (per channel)
   Gain flatness over 200 MHz
  
   Image rejection mixer with quadrature output:
   Amplitude imbalance between IF-channels
   Phase imbalance

   LO-Section:
