MMIC VCO w/ HALF FREQUENCY OUTPUT

& DIVIDE-BY-4, 8.45 - 9.55 GHz

v00.0606

General Description

Features

Functional Diagram

The HMC510LP5 & HMC510LP5E are GaAs InGaP

Heterojunction Bipolar Transistor (HBT) MMIC VCOs.

The HMC510LP5 & HMC510LP5E 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 +13 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 = 8.45 - 9.55 GHz

Fo/2 = 4.225 - 4.775 GHz

Pout: +13 dBm

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

No External Resonator Needed

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
