GaAs SP4T Absorptive Switch 20 MHz–2.5 GHz

The SKY13296-340LF is a pHEMT GaAs FET IC high isolation, absorptive single-pole four-throw switch packaged in a lead (Pb)-free, 4 x 4 mm, 20-lead exposed-pad plastic package for low-cost commercial applications. The use of external DC blocking capacitors on the RF ports and in series with the internal RF terminations enables the user to extend the range of good return loss to arbitrarily low frequency. This switch is an ideal building block for filter bank switching.

Please note: SKY13296-340LF is being discontinued and is not recommended for new designs.


  • Positive voltage control (0/3 V to 0/5 V)
  • High isolation 35 dB at 1 GHz
  • Integrated silicon CMOS driver
  • Isolated ports are absorptive
  • Use of external DC blocks to allow good return loss to low frequency
