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.

This pin is DC coupled. For applications not requiring
operation to DC this port should be DC blocked externally
using a series capacitor. Choose value of capacitor to pass
IF frequency desired. For operation to DC, this pin must
not sink/source more than 40 mA of current or failure may
result.

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.
