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 gure of 2.5
dB and 21 dBc of image rejection. The HMC977LP4E
utilizes a low noise amplier (LNA) followed by an
image reject mixer which is driven by an active 2x
multiplier. The image reject mixer eliminates the need
for a 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. The HMC977LP4E is a
much smaller alternative to hybrid style image reject
mixer downconverter assemblies, and is compatible
with surface mount manufacturing techniques.
The HMC977LP4E is ideal for:
• Point-to-Point and Point-to-Multi-Point Radios
• Military Radar, EW & ELINT
• Satellite Communications
