MMIC VCO w/ BUFFER

AMPLIFIER, 5.8 - 6.8 GHz

v04.0607

General Description

Features

Functional Diagram

The HMC358MS8G & HMC358MS8GE are GaAs

InGaP Heterojunction Bipolar Transistor (HBT) MMIC

VCOs. The HMC358MS8G & HMC358MS8GE inte-

grate resonators, negative resistance devices, varac-

tor diodes, and buffer amplifiers. The VCO’s phase

noise performance is excellent over temperature,

shock, and process due to the oscillator’s monolithic

structure. Power output is 11 dBm typical from a 3V

supply voltage. The voltage controlled oscillator is

packaged in a low cost, surface mount 8 lead MSOP

package with an exposed base for improved RF and

thermal performance.

Pout: +11 dBm

Phase Noise: -110 dBc/Hz @100 KHz

No External Resonator Needed

Single Supply: 3V @ 100 mA

Typical Applications

Low noise MMIC VCO w/Buffer Amplifier

for C-Band applications such as:

• UNII & Pt. to Pt. Radios

• 802.11a & HiperLAN WLAN

• VSAT Radios
