MMIC VCO w/ HALF FREQUENCY OUTPUT

& DIVIDE-BY-4, 9.6 - 10.8 GHz

v00.0407

General Description

Features

Functional Diagram

The HMC512LP5 & HMC512LP5E are GaAs InGaP

Heterojunction Bipolar Transistor (HBT) MMIC VCOs.

The HMC512LP5 & HMC512LP5E 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 +9 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.

Triple Output: Fo = 9.6 - 10.8 GHz

Fo/2 = 4.8 - 5.4 GHz

Fo/4 = 2.4 - 2.7 GHz

Pout: +9 dBm

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

No External Resonator Needed

Typical Applications
