Functional Diagram

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.
