Typical Applications
*Specifi cations are for downconverter performance. Similar results are achieved when using mixer as an upconverter
with a resulting input IP3 of 5dB less.
The HMC304MS8 is a passive IP3 mixer in an 8
lead plastic surface mount Mini Small Outline Pack-
age (MSOP). This miniature single balanced MMIC
mixer is constructed of GaAs Schottky diodes and
novel planar transformer baluns on the chip while
not requiring any external components. The RF port
is balanced via the MMIC balun while the LO port
is connected directly to the diodes. LO isolations
are typically 20 to 30 dB. Excellent input IP3 perfor-
mance of +27 to +32 dBm makes the HMC304MS8
ideal for high dynamic range applications.
The HMC304MS8 is ideal for:
PCS & 3G
2.4 GHz ISM

List of Materials
GaAs MMIC HIGH IP3 SINGLE-
BALANCED SMT MIXER, 1.7 - 3 GHz
The circuit board used in the fi nal 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 below. A suffi cient number of VIA holes
should be used to connect the top and bottom ground
planes. The evaluation circuit board as shown is avail-
able from Hittite upon request.
