1. Introduction
2. User Interface
A 3-way 2.54mm pin header is used for user interface. The pin header (shown in figure 2 below)
connects the terminals (+V
s
, IF, GND) to the amplifier circuits. Any mounting methods deemed suitable
may be used, but the mounting parts should not touch the +V
s
and IF lines and should not be too near to
the patch antennas.
Any pressure or stress to the chassis of the module must be avoided at all, as it may result in change of
module performance.
