3 Circuit Description
This chapter discusses the various functions of the EVM.
3.1 Circuit Function
• Headers TP2 and TP4 supply 5-V V
CC
dc power to the modulator. Header TP4 supplies 5 V to the LO
circuitry, and TP2 supplies 5 V to the modulator circuitry.
• Four SMA connectors are provided on the EVM for inputting differential I/Q signals directly to the input
pins of the TRF370x. Connectors J3, J4, J5, and J6 are used to connect the signal source I/Q signals
directly to the TRF370x.
• Two SMA connectors are provided for LO input: J1 = LOP and J2 = LON. Terminate whichever LO
port is not being used through 50
Ω
to ground.
• One SMA connector is for RF_OUT: J7.
