Features
General Description
The HMC571 is a compact GaAs MMIC I/Q
downconverter chip which provides a small signal
conversion gain of 10 dB with a noise fi gure of 3 dB
and 24 dB of image rejection across the frequency
band. The device utilizes an LNA followed by an image
reject mixer which is driven by an active x2 multiplier.
The image reject mixer eliminates the need for a fi lter
following the LNA, and removes thermal noise at the
image frequency. I and Q mixer outputs are provided
and an external 90° hybrid is needed to select the
required sideband. 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. This product is a much
smaller alternative to hybrid style image reject mixer
downconverter assemblies.
