Functional Block Diagram
Product Description
The TQS5202 is a dualband double-pole double-throw switch
configured for TX-RX and Antenna Diversity switching applications
for the WLAN market. The device exhibits industry-leading
insertion loss, isolation and power handling. It requires no fixed
supply voltage and operates with a positive control voltage. The
switch is manufactured using TriQuint's GaAs pHEMT process and
is packaged in an industry standard 3.0mm x 3.0mm x 0.9mm
VQFN-12 Pb-Free package.
