DESCRIPTION
The SW423R is a broadband single-pole double-throw
(SPDT) antenna switch fabricated with GaAs PHEMT
process. Due to its excellent performance in insertion
loss, isolation and linearity along with the ultra small
form factor and low cost, the device is ideally suited for
applications like IoT and embedded systems.
The SW423R is provided in a miniature 1mm x 1mm x
0.4mm, 6 pin DFN (Dual Flat No-lead) package.
