I signal input. The relationship between
input DC bias and amplitude is as follows :
This is the supply voltage pin for the
direct conversion modulator. The IC
incorporates a band-gap regulator to
provide a regulated bias independent of

removes spurious from the transmission
band by raising up the Lo1 input fre-
