HMC572 General Description

The HMC572 is a compact GaAs MMIC I/Q downconverter chip which provides a small signal conversion gain of 8 dB with a noise fi gure of 3.5 dB and 20 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.

HMC573LC3B General Description

The HMC573LC3B is a x2 active broadband frequency multiplier utilizing GaAs PHEMT technology in a leadless RoHS compliant SMT package. When driven by a +5 dBm signal, the multiplier provides +12 dBm typical output power from 8 to 22 GHz. The Fo and 3Fo isolations are >20 dBc and >25 dBc respectively at 16 GHz. The HMC573LC3B is ideal for use in LO multiplier chains for Pt to Pt & VSAT Radios yielding reduced parts count vs. traditional approaches. The low additive SSB Phase Noise of -134 dBc/Hz at 100 kHz offset helps maintain good system noise performance. The RoHS packaged HMC573LC3B eliminates the need for wire bonding, and allows the use of surface mount manufacturing techniques.
