RoHS Compliant 4x4 mm SMT Package

The HMC525LC4 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 HMC525LC4 eliminates the need

for wire bonding allowing use of surface mount

manufacturing techniques.
