Problem 8 Communication Link: Gain & Loss (14 points) You are given the receiver block as schematically shown below. It consists of a receiving antenna which delivers a signal to a bandpass filter. The antenna feed has a loss of -1.15 dB and the filter's loss is -2.4 dB. The filter's output drives an amplifier with gain of +40.7 dB and this RF signal is input to a mixer which performs a frequency 1translation to an IF signal (but the...
