Description
M/A-COM's SW-395 is a GaAs single pole, double throw switch in a low cost SOT-26 surface mount plastic package. The SW-395 is ideally suited for applications where very low power consumption, low intermodulation products, very small size and low cost are required. Typical application is an internal / external antenna select switch for portable telephones and data radios. In addition, because of its low loss, good isolation and inherent speed, the SW-395 can be used as a conventional T/R switch or as an antenna diversity switch. The SW-395 can be used in power applications up to 0.5 Watts in systems such as cellular, PCS, GSM and other analog / digital wireless communications systems. The SW-395 is fabricated using a mature 0.5-micron gate length GaAs PHEMT process. The process features full chip passivation for increased performance and reliability.

6. Exceeding any one or combination of these limits may cause permanent damage to this device. 7. M/A-COM does not recommend sustained operation near these survivability limits.
2. For positive voltage control, external DC blocking capacitors are required on all RF ports. 3. 0 = -8 V to 0 V, 1 = 0 V to +8 V. 4. Differential voltage, V (state 1) - V (state 0), must be +2.8 V minimum and must not exceed +8 V.
