Functional Diagram

General Description

The HMC568LC5 is a compact GaAs MCM I/Q

downconverter in

leadless RoHS compliant

SMT package. This device provides a small signal

conversion gain of 14 dB with a noise ﬁgure of 2 dB and

33 dB of image rejection. The HMC568LC5 utilizes an

LNA followed by an image reject mixer which is driven

by an LO buffer ampliﬁer. 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

HMC568LC5 is a much smaller alternative to hybrid

style image reject mixer downconverter assemblies,

and it eliminates the need for wire bonding by allowing

the use of surface mount manufacturing techniques.
