MMIC VCO w/ HALF FREQUENCY

OUTPUT 7.3 - 8.2 GHz

v04.0811

General Description

Features

Functional Diagram

The HMC508LP5 & HMC508LP5E are GaAs InGaP

Heterojunction Bipolar Transistor (HBT) MMIC

VCOs. The HMC508LP5 & HMC508LP5E integrate

resonators, negative resistance devices, varactor

diodes and feature a half frequency output. The VCO’s

phase noise performance is excellent over temper-

ature, shock, and process due to the oscillator’s

monolithic structure. Power output is +15 dBm typical

from a +5V supply. The voltage controlled oscillator

is packaged in a leadless QFN 5x5 mm surface

mount package, and requires no external matching

components.

Dual Output: Fo = 7.3 - 8.2 GHz

Fo/2 = 3.65 - 4.1 GHz

Pout: +15.0 dBm

Phase Noise: -116 dBc/Hz @100 kHz Typ.

No External Resonator Needed

32 Lead 5x5mm SMT Package: 25mm²

Typical Applications

Low noise MMIC VCO w/Half Frequency, for:

• VSAT Radio

• Point to Point/Multi-Point Radio

• Test Equipment & Industrial Controls

• Military End-Use
