Typical Applications
The HMC136 is suitable for:
Wireless Local Loop
LMDS & VSAT
Point-to-Point Radios
Test Equipment
The HMC136 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 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.
