HMC304MS8
GaAs MMIC HIGH IP3 SINGLE-
BALANCED SMT MIXER, 1.7 - 3 GHz
Features
High Dynamic Range: +30 dBm IIP3
No External Components or Bias Required
LO/RF Isolation: 30 dB
Ultra Small MSOP8 Package: 14.8 mm
General Description
The HMC304MS8 is a passive 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 the HMC304MS8
ideal for high dynamic range applications.
