Fig.5 Input circuit for minimum noise figure.

(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 (5.5 mm, wire diameter = 0.5 mm).

l1 = rigid cable (RIM): 5 cm long

(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 = rigid cable (RIM): 30 cm long.

l3 = rigid cable (RIM): 5 cm long

(rigid cable (RIM); 33 dB/100 m; 50

Ω; 96 pF/m).
