HMC188MS8

GaAs MMIC SMT PASSIVE FREQUENCY

DOUBLER, 1.25 - 3.0 GHz INPUT

v02.1201

General Description

Features

Functional Diagram

Conversion Loss: 15 dB

Fo, 3Fo, 4Fo Isolation: 45 dB

Input Drive Level: 10 to 20 dBm

Typical Applications

The HMC188MS8 is suitable for:

• Wireless Local Loop

• LMDS, VSAT, and Pt to Pt Radios

• UNII & HiperLAN

• Test Equipment

The HMC188MS8 is a miniature frequency doubler

in a plastic 8-lead MSOP package. The suppres-

sion of undesired fundamental and higher order har-

monics is 45 dB typical with respect to input signal

levels. The doubler uses the same diode/balun tech-

nology used in Hittite MMIC mixers. The doubler is

ideal for high volume applications where frequency

doubling of a lower frequency is more economical

than directly generating a higher frequency. The

passive Schottky diode doubler technology contrib-

utes no measurable additive phase noise onto the

multiplied signal.
