MMIC VCO w/ HALF FREQUENCY OUTPUT

& DIVIDE-BY-4, 11.17 - 12.02 GHz

v03.0811

General Description

Features

Functional Diagram

The HMC514LP5 & HMC514LP5E are GaAs InGaP

Heterojunction Bipolar Transistor (HBT) MMIC VCOs.

The HMC514LP5 & HMC514LP5E 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 tem-

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

monolithic structure. Power output is +7 dBm typical

from a +3V supply voltage. The prescaler function 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 = 11.17 - 12.02 GHz

Fo/2 = 5.58 - 6.01 GHz

Pout: +7 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:

• VSAT Radio

• Point to Point/Multipoint Radio

• Test Equipment & Industrial Controls

• Military End-Use
