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
constru cted of GaAs Schot tky diod es 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  nal application
should use RF circuit design techniques. Signal
lines should have 50 ohm impedance while the
package ground leads and exposed padd le should
be connected directly to the ground plane similar
to that shown. A suf cient 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.
