HMC434

Data Sheet 0.2 GHz to 8 GHz, GaAs, HBT MMIC, Divide by 8 Prescaler HMC434 FEATURES Ultralow SSB phase noise: −150 dBc/Hz typical Single-ended input/outputs Output power: −2 dBm typical Single supply operation: 3 V Ultrasmall, surface-mount, 2.90 mm × 2.80 mm, 6-lead SOT-23 package APPLICATIONS DC to C band PLL prescalers Very small aperture terminal (VSAT) radios Unlicensed national information infrastructure (UNII) and point to point radios IEEE 802.11a and high performance radio local area network (HiperLAN) WLAN Fiber optics Cellular/3G infrastructure GENERAL DESCRIPTION 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. FUNCTIONAL BLOCK DIAGRAM VCC HMC434 IN ÷8 OUT 15684-001 GND Figure 1. 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. Rev.
