This chapter discusses the various functions of the EVM.
•
Headers W1 and W2 supply 5-V V
CC
dc power to the modulator. Header W1 supplies 5 V to the LO
circuitry, and W2 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 TRF3703. Connectors J3, J4, J5, and J6 are used to connect the signal source I/Q signals
directly to the TRF3703.
•
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.
