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.
