This is the local input to the orthogonal
modulator. The input impedance is
10k
.
Lo1
Pin No.
An external LC connected to this pin
removes spurious from the transmission
band by raising up the Lo1 input fre-
quency band. The output is an emitter
follower.
This is a local input to the UP mixer.
An external balance coil should be used
to provide balanced input.
This is a local input to the UP mixer.
An external balance coil should be used
to provide balanced input.
This is the ground for the orthogonal
modulator. The ground foil pattern for
this pin must be wide enough to provide
a low impedance.
