(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 Ω; 96 pF/m).
(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 = 25 pF.
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 Ω; 96 pF/m).
