PHASE-LOCKED OSCILLATOR,

14.7 - 15.4 GHz

v01.1009

General Description

Features

Functional Diagram

The HMC535LP4 & HMC535LP4E are GaAs InGaP

Heterojunction Bipolar Transistor (HBT) MMIC PLOs.

The PLO’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. All fun-

ctions (VCO, Op-Amp, PFD, Prescaler) are fully

integrated while providing allowances for off-chip

customer specific loop components. The PLO MMIC

accepts a single-ended or a differential reference

oscillator input signal in the range of 230 to 240 MHz,

and a digital Lock Detector (LD) output is provided

to confirm the status of the loop. The phase-locked

oscillator is packaged in a leadless QFN 4 x 4 mm

surface mount package.

Pout: +9 dBm

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

Single Supply: +5V @ 340 mA

+12V @ 28 mA

Typical Applications

Phase-Locked Oscillator for:

• VSAT Radio

• Point-to-Point & Point-to-Multi-Point Radio

• Test Equipment & Industrial Controls

• Military End-Use
