It is also ideal for other applications where a com-
pact, high performance, symmetrical SP3T switch
is required.
The design is symmetric and has been fully
optimized for excellent cross modulation perform-
ance in all three paths while still maintaining excel-
lent insertion loss and isolation. The symmetrical
design allows the user to assign CDMA Cellular,
PCS and AWS to ports RF1, RF2 or RF3 as
required to optimize the layout.
The MASW-009482 is fabricated using a 0.5 micron
gate length GaAs pHEMT process. The process
features full passivation for performance and
reliability.
