HMC431LP4 Amplifier

General Description

The HMC431LP4 & HMC431LP4E are GaAs InGaP Heterojunction Bipolar Transistor (HBT) MMIC VCOs with integrated resonators, negative resistance devices, varactor diodes, and buffer amplifi ers. The
VCO’s phase noise performance is excellent over temperature, shock, vibration and process due to the oscillator’s monolithic structure. Power output is 2 dBm typical from a 3V supply voltage. The voltage controlled oscillator is packaged in a low cost leadless QFN 4 x 4 mm surface mount package.

Features

Pout: +2 dBm
Phase Noise: -102 dBc/Hz @100 kHz
No External Resonator Needed
Single Supply: 3V @ 27 mA
16mm2 Leadless SMT Package

Typical Applications

Low noise MMIC VCO w/Buffer Amplifi er
for C-Band applications such as:
• 802.11a & HiperLAN WLAN
• VSAT Radios
• UNII & Point-to-Point Radios
