General Description
The HMC977LP4E is a compact GaAs MMIC I/Q
downconverter in a leadless RoHS compliant
SMT package. This device provides a small signal
conversion gain of 14 dB with a noise figure of 2.7
dB and 21 dBc of image rejection. The HMC977LP4E
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 filter 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. The
HMC977LP4E is a much smaller alternative to hybrid
style image reject mixer downconverter assemblies,
and is compatible with surface mount manufacturing
techniques.
