The non-inverting input to the transmit filter
stage
The inverting input to the transmit filter stage
The output used for gain adjustments of the
transmit filter
The low power receive filter output This pin can
directly drive the receive port of an electronic hy-
brid
The input to the receive filter differential power
amplifier
The non-inverting output of the receive filter pow-
er amplifier This output can directly interface
conventional transformer hybrids
The inverting output of the receive filter power
amplifier This output can be used with PWRO
to differentially drive a transformer hybrid
