MMIC VCO w/ BUFFER

AMPLIFIER, 2.6 - 2.8 GHz

v01.0604

General Description

Features

Functional Diagram

The HMC386LP4 is a GaAs InGaP Heterojunction

Bipolar

Transistor

(HBT)

MMIC

VCO

with

integrated resonator, negative resistance device,

varactor diode, and buffer amplifier. Covering 2.6

to 2.8 GHz, the VCO’s phase noise performance

is excellent over temperature, shock, vibration

and process due to the oscillator’s monolithic

structure. Power output is 5 dBm typical from

a single supply of 3V @ 35mA.

The voltage

controlled oscillator is packaged in a low cost

leadless QFN 4 x 4 mm surface mount package.

Pout: +5 dBm

Phase Noise: -114 dBc/Hz @100 kHz

No External Resonator Needed

Single Supply: 3V @ 35 mA

Typical Applications

Low noise MMIC VCO w/Buffer Amplifier for:

• Wireless Infrastructure

• Industrial Controls

• Test Equipment

• Military
