HMC521LC4

射频混合器 GaAs MMIC I/Q mix / IRM , 8.5 - 13.5 GHz

GaAs MMIC I/Q MIXER  8.5 - 13.5 GHz

General Description

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.

Typical Applications

The HMC521LC4 is ideal for:

• Point-to-Point and Point-to-Multi-Point Radio

• Military Radar
