General Description

The HMC522 is a compact I /Q MMIC mixer which can be used as either an Image Reject Mixer or a Single Sideband Upconverter. The chip utilizes two standard Hittite double balanced mixer cells and a 90 degree hybrid fabricated in a GaAs MESFET process. All data shown below is taken with the chip mounted in a 50 Ohm test fi xture and includes the effects of 1 mil diameter x 20 mil length bond wires on each port. 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.

Features

Wide IF Bandwidth: DC - 3.5 GHz

Image Rejection: 35 dB

LO to RF Isolation: 45 dB

High Input IP3: +24 dBm

Typical Applications

The HMC522 is ideal for:

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

• Digital Radio

• VSAT
