HMC135 is a GaAs MMIC Bi-Phase Modulator produced by Hittite. It can be directly integrated into MIC circuits, directly modulated in the 1.8-5.2 GHz band, and has a carrier suppression ratio of 30 dB. The device can also be used as a phase detector.
The HMC135 is a GaAs MMIC Bi-Phase Modulator designed for frequencies between 1.8 and 5.2 GHz. It integrates directly into microwave designs to phase-modulate RF signals into reference and 180-degree states, providing 30 dB of carrier suppression. The device also functions as a phase detector or demodulator.
