General Description
The HMC304MS8 is a passive level 17 high IP3
mixer in an 8 lead plastic surface mount Mini
Small Outline Package (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
performance of +27 to +32 dBm makes this
device ideal for PCS, 3G, 2.4 GHz ISM, or
MMDS applications. The HMC304MS8 is the
smallest high IP3 mixer available in the market,
0.118"x 0.190" (3.0 mm x 4.9 mm).
