(a) For fRF = 50 MHz:
mixer A frequency response measured = 57 MHz, loss = 0 dB
image suppression = 16 dB
C1 = 9 pF
C2 = 15 pF
L1 = 7 turns (diameter = 5.5 mm, wire diameter = 0.5 mm)
l1 = semi rigid cable (RIM): 5 cm long
(semi rigid cable (RIM); 33 dB/100 m; 50

(b) For fRF = 150 MHz:
mixer A frequency response measured = 150.3 MHz, loss = 1.3 dB
image suppression = 13 dB
C3 = 5 pF
C4 =25pF
l2 = semi rigid cable (RIM): 30 cm long
l3 = semi rigid cable (RIM): 5 cm long
(semi rigid cable (RIM); 33 dB/100 m; 50
; 96 pF/m).
