Description
The AW004R2-93 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.

The "chip on board" package is a ceramic leadless chip carrier with a ceramic
lid, which allows for automatic pick and place. The external terminals and
backside ground plane are Pt/Pd/Ag, which is highly leach resistant and very
tolerant to variations in solder conditions. The glass fingers between contacts
prevent the possibility of shorted terminals. The recommended solder
attachment is a SN6337 (Pb/SN).
