Description
The MASW-008322 is a versatile, broadband, high
isolation SPDT switch offered in a lead-free 4 mm
24-lead PQFN surface mount plastic package. The
design incorporates both series and shunt circuit
elements with the locations optimized to achieve
outstanding broadband performance to 20 GHz.
The combination of broadband performance along
with very fast switching and excellent settling time
make this device ideal for many applications,
including Test & Measurement, EW and broadband
communication systems.
The MASW-008322 is fabricated using M/A-COM
Technology’s mature 0.5um Low Gate-Lag pHEMT
process. This robust process features full surface
passivation for a high performance and high
reliability.
