MMIC VCO w/ HALF FREQUENCY OUTPUT

& DIVIDE-BY-4, 13.6 - 14.9 GHz

v00.1105

General Description

Features

Functional Diagram

The HMC531LP5 & HMC531LP5E are GaAs InGaP

Heterojunction Bipolar Transistor (HBT) MMIC VCOs.

The HMC531LP5 & HMC531LP5E 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 +7 dBm typical

from a +5V 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 = 13.6 - 14.9 GHz

Fo/2 = 6.8 - 7.45 GHz

Pout: +7 dBm

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

No External Resonator Needed

Typical Applications
