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.

The circuit board used in the final application should use RF circuit design techniques. Signal lines should have 50 ohm impedance while the package ground leads and exposed paddle should be connected directly to the ground plane similar to that shown. A sufficient number of via holes should be used to connect the top and bottom ground planes. The evaluation circuit board shown is available from Hittite upon request.
