This section provides a step-by-step guide for operat-
ing the EV kit and testing all four major functions: the
LNA, receive mixer, transmit mixer, and PA driver. Do
not turn on the DC power or RF signal generators
until all connections are made.
1) Set the RXEN jumper on the EV kit to the “Logic 1”
2) Connect a DC supply set to 3V (through an amme-
3) Connect one RF signal generator with the output
4) Connect a spectrum analyzer to the LNAOUT SMA
5) Turn on the DC supply. The supply current should
6) Enable the RF generator’s output. A signal on the
7) If desired, the shutdown feature can be tested by
1) Disable the output of the RF signal generator. Turn
2) Set the RXEN jumper on the EV kit to the “Logic 1”
3) Connect one RF signal generator (with the output
