General Description
The HMC135 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 output 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 30 dB of carrier suppression in
a tiny monolithic 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 signals 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.
