GaAs IC 2 Watt High Linearity SPDT Switch DC-2 GHz AS359-62 Features High Linearity (55 dBm IP3 @ 0.9 GHz) SSOP-8 Low Insertion Loss (0.35 dB @ 0.9 GHz) 0.220 (5.60 mm) 0.197 (5.00 mm) Antenna Changeover and T/R Cellular Switch 0.323 (8.20 mm) 0.291 (7.40 mm) PIN 1 INDICATOR Description The AS359-62 is a GaAs FET IC SPDT switch in an SSOP-8 plastic package. The switch has been designed for use where extremely high linearity and low insertion loss are required. It can be controlled with positive, negative or a combination of both voltages. Some standard implementations include antenna changeover, T/R and diversity switching over 2 W. The AS359-62 switch can be used in many analog and digital wireless communication systems including cellular, GSM and DECT applications. 0.0256 (0.65 mm) TYP. 0.129 (3.30 mm) R 0.004 R 0.004 0.106 (2.70 mm) (0.10 mm) (0.10 mm) MIN.
