HMC521LC4

GaAs MMIC I/Q MIXER

8.5 - 13.5 GHz

v03.0709

General Description

Features

Typical Applications

The HMC521LC4 is a compact I/Q MMIC mixer in a

leadless “Pb free” RoHS compliant SMT package,

which can be used as either an Image Reject Mixer

or a Single Sideband Upconverter. The mixer utilizes

two standard Hittite double balanced mixer cells and

a 90 degree hybrid fabricated in a GaAs MESFET

process. A low frequency quadrature hybrid was used

to produce a 100 MHz USB IF output. This product is a

much smaller alternative to hybrid style Image Reject

Mixers and Single Sideband Upconverter assemblies.

The HMC521LC4 eliminates the need for wire

bonding allowing use of surface mount manufacturing

techniques.
