GaAs IC Diversity Switch DC–2.5 GHz ASC02D2-12 (Previously ADC02D2-12)* Features SOIC-8 ■ Low Cost SOIC-8 Plastic Package PIN 8 0.050 (1.27 mm) BSC ■ Independent Four Port Switching ■ Individual Voltage Control on Each Port 0.244 (6.20 mm) 0.228 (5.80 mm) PIN 1 INDICATOR Description The ADC02D2 is a 4 port switch with independent DC voltage control on each port mounted in the SOIC-8 package. In transmit or receive applications, the asymmetric design allows for good isolation between transmit and receive path while maintaining medium power handling in transmit port.
