Product Description:
The TQS5201 is a high power, double-pole double-throw switch configured for
TX-RX or 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 3mm x 3mm VQFN-12 package.
