HMC204C8

GaAs MMIC SMT PASSIVE FREQUENCY

DOUBLER, 4 - 8 GHz INPUT

General Description

Features

Functional Diagram

Conversion Loss: 16 dB

Fo, 3Fo, 4Fo Isolation: 40 dB

Passive: No Bias Required

Typical Applications

The HMC204C8 is suitable for:

• Wireless Local Loop

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

• Test Equipment

The HMC204C8 is a passive miniature frequency

doubler in a non-hermetic surface mount package.

Suppression of undesired fundamental and higher

order harmonics is 40 dB typical with respect to input

signal level. The doubler utilizes the same GaAs

Schottky diode/balun technology found in Hittite

MMIC mixers. It features small size, no DC bias, and

no measurable additive phase noise onto the multi-

plied signal.

Input = +10 dBm

Input = +13 dBm
