Description
M/A-COM’s MASWSS0115 is a GaAs PHEMT
MMIC single pole, double throw (SPDT) switch in a
low cost, lead-free SC-70 (SOT-363) surface mount
plastic package. The MASWSS0115 is ideally suited
for applications where very small size and low cost
are required.
Typical applications are dual band systems which
require switching between small signal components
such as filter banks, single-band LNAs, converters,
etc. This part can be used for low power, low loss
requirements in all systems operating up to 3 GHz,
including PCS, GSM, DCS, Blue Tooth, and other
receive chain applications.

6. External DC blocking capacitors are required on all RF ports.
7. 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 - 3 GHz.
