Description
M/A-COM’s MASWSS0204 is a GaAs PHEMT
MMIC single pole double throw (SPDT) high power
switch in a low cost SC70 six lead package. The
MASWSS0204 is ideally suited for applications
where high power, low control voltage, low insertion
loss, high isolation, small size and low cost are
required.
Typical applications are for CDMA handset
systems that connect separate transceiver and/or
GPS functions to a common antenna, as well as
other related handset and general purpose
applications. The MASWSS0204 can be used in all
systems operating up to 3 GHz requiring high power
at low control voltage.
The MASWSS0204 is fabricated using a 0.5 micron
gate length GaAs PHEMT process. The process
features full passivation for performance and
reliability.

1. For positive voltage control, external DC blocking capacitors are required on all RF ports.
2. Insertion loss can be optimized by varying the DC blocking capacitor value, e.g. 1000 pF for 100 MHz - 1 GHz, 39 pF for 0.5 GHz - 3 GHz.
