Preliminary Technical Data
EVALUATION BOARD
An evaluation board is available for the ADL5350. The evaluation board has two halves: a low band designated as Board A, and a high
band board designated as Board B. The schematic for the evaluation board is presented in Figure 65.

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 Amp Choke.
Provides bias and ac loading impedance to LO buffer amp.
