MMIC VCO w/ HALF FREQUENCY OUTPUT

& DIVIDE-BY-4, 10.6 - 11.8 GHz

v03.0811

General Description

Features

Functional Diagram

The HMC534LP5 & HMC534LP5E are GaAs InGaP

Heterojunction Bipolar Transistor (HBT) MMIC VCOs.

The HMC534LP5 & HMC534LP5E integrate resona-

tors, negative resistance devices, varactor diodes

and feature half frequency and divide-by-4 outputs.

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 +5V supply voltage. The prescaler and RF/2

functions can be disabled to conserve current if not

required. The voltage controlled oscillator is packaged

in a leadless QFN 5x5 mm surface mount package,

and requires no external matching components.

Dual Output: Fo = 10.6 - 11.8 GHz

Fo/2 = 5.3 - 5.9 GHz

Pout: +11 dBm

Phase Noise: -110 dBc/Hz @100 kHz Typ.

No External Resonator Needed

32 Lead 5x5mm SMT Package: 25mm²

Typical Applications

Low noise MMIC VCO w/Half Frequency, Divide-by-4

Outputs for:

• Point to Point/Multipoint Radio

• Test Equipment & Industrial Controls

• SATCOM

• Military End-Use
