Add an additional 6dB to the voltage gain to account
for the 2:1 transformer on the output. Add another
3.96dB to the voltage gain to account for the minimum
loss pad (R10 and R11) on the input. When measuring
noise figure, account for 5.7dB power loss of the mini-
mum loss pad.
A 36MHz IF anti-aliasing filter is provided on the EV kits
(C9, C12, C21, C25, C28, C29, C31, C35, L3, L9, L10,
and L11). Anti-aliasing filter requirements vary depend-
ing on applications; users should consult their demodu-
lator vendors for more specific information.

Gain Adjustment Calculations
The MAX3541/MAX3542 EV kits serve as a guide for
PCB layout. Keep RF signal lines as short as possible
to minimize losses and radiation. Use controlled imped-
ance on all high-frequency traces. The exposed pad
must be soldered evenly to the board’s ground plane
for proper operation. Use abundant vias beneath the
exposed pad for maximum heat dissipation. Use abun-
dant ground vias between RF traces to minimize unde-
sired coupling.
To minimize coupling between different sections of the
IC, the ideal power-supply layout is a star configuration,
which has a large decoupling capacitor at the central
V
with each trace going to separate V
