(VCO) from the PA, and reducing the demands of
designing a high-frequency VCO. An internal LO band-
pass filter is integrated after the frequency doubler to
help reduce LO harmonic content and spurious mixing.
To enable the LO frequency doubler, drive
ENX2
to a
logic-low level and connect the half-frequency external
LO to the LOX2 port. To disable and bypass the LO fre-
quency doubler and LO filter, drive
ENX2
to a logic-
high level and connect the full-frequency external LO to
