Typical Applications
The HMC135 is suitable for:
Wireless Local Loop
LMDS & VSAT
Pt. to Pt. Radios
Test Equipment
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) defi nes the phase states. Excel-
lent 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 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.
