v04.0909 HMC135 GaAs MMIC BI-PHASE MODULATOR, 1.8 - 5.2 GHz MODULATORS - BI-PHASE - CHIP 5 5-2 Typical Applications Features The HMC135 is suitable for: Chip Integrates Directly into MIC Designs Wireless Local Loop Carrier Suppression: 30 dB LMDS & VSAT Direct Modulation in the 1.8 - 5.2 GHz Band Point-to-Point Radios Functions also as a Phase Detector Test Equipment SOLETE Functional Diagram Die Size: 1.45 x 1.45 x 0.1 mm 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.
