Analog Devices HMC137

The HMC137 is suitable for: Chip Integrates Directly into MIC Designs • Wireless Local Loop Carrier Suppression: 20 dB • LMDS & VSAT Direct Modulation in the 6 - 11 GHz Band • Point-to-Point Radios Functions also as a Phase Detector • Test Equipment SOLETE Functional Diagram Die Size: 1.45 x 1.30 x 0.1 mm General Description The HMC137 Bi-Phase Modulator is designed to phase-modulate an RF signal into reference and 180 degree states. The polarity of the bias current at the control port (IF port) defines the phase states. The device also functions as a demodulator or phase comparator.

APPLICATIONS

FEATURES

Device input is at the RF port and output is at the LO port. Excellent amplitude and phase balance provided by closely matched monolithic balun and diode circuits delivers 20 dB of carrier suppression in a tiny monolithic chip. 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. B
