Functional Diagram
General Description
The HMC304MS8 & HMC304MS8E are passive
high IP3 mixers in 8 lead plastic surface mount Mini
Small Outline Packages (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
make the HMC304MS8(E) ideal for high dynamic
range applications.
