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