Typical Applications

Public Safety, IEEE 802.11a, WiMax, HIPERLAN and military radio, military
Description
 

The design experience described here is a high power high isolation double pole double throw low diode switch. It combines the functionality of transmit-receive switch, diversity switch and low pass filters for harmonic rejections. It is suitable up to power level of 40 dBm. The switch is fabricated with 4 mil GaAs process with four PIN diode chips. The concept can be easily ported to other frequency of operation and larger power levels.

Key Features
  • 4-Port PIN diode switch
  • Includes LPF's for antenna 1 & 2
  • Low insertion loss -1.7 dB @ 4.95 GHz
  • Isolation 30 dB @ 4.95 GHz
  • GaAs passive substrate
  • Fast switching four PIN diode chips
  • 50 ohm impedance
  • +5/-5 V voltage control
  • High power application till 40 dBm
