Function
Supply Decoupling. C4-A and C4-B provide local bypassing of the supply.
C5-A and C5-B are used to filter the ripple of a noisy supply line. These are not
always necessary.
RF Input Network. Designed to provide series resonance at the intended
RF frequency.
IF Output Network. Designed to provide parallel resonance at the geometric mean
of the RF and LO frequencies.
LO Input Network. Designed to block dc and optimize LO voltage swing at LOIN.
LO Buffer Amplifier Choke. Provides bias and ac loading impedance to LO buffer
amplifier.
