spectrum analyzer should read about -15dBm at
110MHz. In all other modes, the peak should be
about -13dBm at 210MHz. Be sure to account for
cable losses (between 0.5dB and 2dB) and circuit
board losses (approximately 0.5dB) when comput-
ing gain and noise figure.

The EV kit PC board can serve as a guide for layout
using the MAX2320/21/22/24/26/27.
Keep traces carrying RF signals as short as possible to
minimize radiation and insertion loss due to the PC
board. Keep the differential mixer output traces togeth-
er and of equal length to ensure signal amplitude bal-
ance. Solder the entire bottom side slug evenly to the
board ground plane for best RF performance. Run the
input trace to the PCS LNA on the top layer of the PC
board avoiding via-induced coupling. Minimize the par-
allel length of the cellular LNA input trace with the PCS
LNA input trace.
