Functional Diagram
General Description
The HMC350MS8 & HMC350MS8E are miniature
single balanced mixers in 8 lead plastic surface mount
packages. The passive GaAs schottky diode mixer
implements planar on chip baluns and requires no
external components. The mixer can be used as an
upconverter, down converter, or modulator. The mixer
provides 7.5 dB conversion loss and +25 dBm IIP3 with
LO drive levels of +19 dBm at mid-band. The design
was optimized for low cost high volume applications
where high converter linearity is required.

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 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
as shown is available from Hittite upon request.
