Functional Diagram
General Description
The HMC560LM3 is a 24 - 40 GHz passive, double-
balanced MMIC mixer in a SMT leadless chip carrier
package. The mixer is fabricated in a GaAs MESFET
process, and can be used as a downconverter or
upconverter. The wide operating bandwidth allows this
device to be used across multiple radio bands with a
common platform. Excellent isolations are provided by
on-chip baluns. The HMC560LM3 requires no external
components and no DC bias. All data is with the
non-hermetic, epoxy sealed LM3 package mounted
in a 50 Ohm test fixture. Utilizing the HMC560LM3
eliminates the need for wirebonding, thereby providing
a consistent connection interface for the customer,
and allowing the use of surface mount manufacturing
techniques.
