Functional Diagram
General Description
The
HMC277MS8
&
HMC277MS8E
are
general purpose single balanced mixers in 8
lead plastic surface mount Mini Small Outline
Packages (MSOP). This passive MMIC mixer is
constructed of GaAs Schottky diodes and a novel planar
transformer balun on the chip. The HMC277MS8(E)
requires no external matching components, and is ideal
for upconverter and downconverter applications.The
RF port is balanced via the MMIC balun while the LO
port is connected directly to the diodes. This product is
pin for pin compatible with the HMC272MS8(E) which
operates from 1.7 to 3.0 GHz.
