HMC208MS8
General Description
The HMC208MS8 is an ultra miniature double-
balanced mixer in an 8 lead plastic surface
mount Mini Small Outline Package (MSOP).
This passive MMIC mixer is constructed of
GaAs Schottky diodes and novel planar trans-
former baluns on the chip. The device can be
used as a up, or downconverter, bi-phase
(de)modulator or phase comparator for 900,
1500, or 1900 MHz applications. It is especially
suited for miniature basestations, PCMCIA
transceivers, cable modems, and portable wire-
less applications because of its high dynamic
input signal range, small size, and zero DC bias
requirement. The consistent MMIC performance
will improve system operation and assure regu-
latory compliance. The MSOP8 package is the
smallest footprint available for a complete double-
balanced mixer, 0.118” x 0.190” (3.0mm x
4.9mm). At a height of 0.040” (1.0mm) this is the
thinnest
mixer package available today.
