Description
0.056
The AH004R2-93 is an IC FET SPDT switch in a low cost
“chip on board” package. It features extremely high
linearity, low insertion loss, with very low DC power
consumption. Some standard implementations include
antenna changeover, T/R and diversity switching over 2 W.
This switch can be used in many analog and digital
wireless communication systems.
