Description
The AS018M2-00 GaAs SPDT matched MMIC FET
switch chip is ideal for applications requiring low loss, high
isolation and/or broadband operation. The GaAs MMIC
employs three shunt and two series FETs per arm for low
loss, high isolation switching together with a 50
load
which is switched into the high isolation arm for low return
loss. Power consumption is very low, typically 75
A at
-5 V. While recommended for operation up to 18 GHz, the
switch performs well through 22 GHz.
