GaAs MMIC SMT PASSIVE FREQUENCY

DOUBLER, 1.25 - 3.0 GHz INPUT

v04.0709

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 / HMC188MS8E is suitable for:

• Wireless Local Loop

• LMDS, VSAT, and Point-to-Point Radios

• UNII & HiperLAN

• Test Equipment

The HMC188MS8 & HMC188MS8E are miniature

frequency doublers in plastic 8-lead MSOP packages.

The suppression of undesired fundamental and higher

order harmonics is 45 dB typical with respect to input

signal levels. The doubler uses the same diode/balun

technology 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 contributes no

measurable additive phase noise onto the multiplied

signal.
