MMIC VCO w/ HALF FREQUENCY OUTPUT

& DIVIDE-BY-4, 14.25 - 15.65 GHz

v00.0707

General Description

Features

Functional Diagram

The HMC632LP5(E) is a GaAs InGaP Heterojunc-

tion Bipolar Transistor (HBT) MMIC VCO. The

HMC632LP5(E)

integrates

resonators,

negative

resistance devices, varactor diodes and features 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.

Dual Output: Fo = 14.25 - 15.65 GHz

Fo/2 = 7.125 - 7.825 GHz

Pout: +9 dBm

Phase Noise: -107 dBc/Hz @100 kHz Typ.

No External Resonator Needed

Typical Applications

The HMC632LP5(E) is ideal for:

• Point to Point/Multipoint Radio

• Test Equipment & Industrial Controls

• SATCOM

• Military End-Use
