0.2 GHz to 8 GHz, GaAs, HBT MMIC, Divide by 8 Prescaler

The HMC434 is a low noise, static, divide by 8 prescaler monolithic microwave integrated circuit (MMIC) utilizing indium gallium phosphide/gallium arsenide (InGaP/GaAs) heterojunction bipolar transistor (HBT) technology in an ultrasmall surface-mount 6-lead SOT-23 package.

The HMC434 operates from near dc (square wave) or 200 MHz (sine wave) to 8 GHz input frequency with a single 3 V dc supply.

The HMC434 features single-ended inputs and outputs for reduced component count and cost. The low additive single sideband (SSB) phase noise of −150 dBc/Hz at 100 kHz offset helps the user maintain optimal system noise performance.
