HMC204C8

GaAs MMIC SMT PASSIVE FREQUENCY

DOUBLER, 4 - 8 GHz INPUT

Features

Conversion Loss: 16 dB

Fo, 3Fo, 4Fo Isolation: 40 dB

Passive: No Bias Required

General Description

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
multiplied signal.

HMC204C8

GaAs MMIC SMT FREQUENCY

DOUBLER, 4 - 8 GHz INPUT

The circuit board used in the fi nal application should be generated with proper RF circuit design techniques.
Signal lines should have 50 ohm impedance while the package ground leads and exposed paddle should be
connected directly to the ground plane similar to that shown. The evaluation circuit board shown is available from
Hittite upon request.
