MMIC VCO w/ DIVIDE-BY-4

10.5 - 12.2 GHz

v03.0609

General Description

Features

Functional Diagram

The HMC735LP5(E) is a GaAs InGaP Heterojunc-

tion Bipolar Transistor (HBT) MMIC VCO. The

HMC735LP5(E)

integrates

resonators,

negative

resistance devices, varactor diodes and features a

divide-by-4 frequency output. The VCO’s phase noise

performance is excellent over temperature, shock,

and process due to the oscillator’s monolithic

structure. Power output is +17 dBm typical from a

+5V supply voltage. The prescaler function can be dis-

abled 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 = 10.5 - 12.2 GHz

Fo/4 = 2.625 - 3.05 GHz

Pout: +17 dBm

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

No External Resonator Needed

Typical Applications

The HMC735LP5(E) is ideal for:

• Point-to-Point/Multi-Point Radio

• Test Equipment & Industrial Controls

• SATCOM

• Military End-Use
