Functional Diagram
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 fixture 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.
Electrical Specifications, TA = +25° C, IF= 100 MHz, LO = +15 dBm*
