General Description
The HMC137 Bi-Phase Modulator is designed to
phase-modulate an RF signal into reference and 180
degree states. Device input is at the RF port and out-
put is at the LO port. The polarity of the bias current
at the control port (IF port) defines the phase states.
Excellent amplitude and phase balance provided by
closely matched monolithic balun and diode circuits
delivers 20 dB of carrier suppression in a tiny mono-
lithic chip.
The device also functions as a demodulator or phase
comparator. As a demodulator, data emerges at the
control port when a modulated signal at the RF port
is compared to a reference signal at the LO port. As a
phase comparator, the phase angle between two sig-
nals applied to the RF and LO ports is represented
by an analog voltage at the control port. Except for
carrier suppression, the data presented here was
measured under static conditions in which a DC bias
current (nominally 5 mA) is applied to the control port.
