Description
M/A-COM’s MASWSS0143 is a GaAs monolithic switch in a lead-free, SOT-26 surface mount plastic package. The MASWSS0143 is ideally suited for applications where very low power consumption, low intermodulation products and very small size are required. Typical applications include internal / external antenna select switch for portable telephones and data radios. In addition because of its low loss, good isolation, and inherent speed, the MASWSS0143 can be used as a conventional T/R switch or as an antenna diversity switch. The MASWSS0143 can be used in power applications up to 3 watts in systems such as cellular PCS, CDMA, W-CDMA, TDMA, GSM and other analog / digital wireless communications systems. The MASWSS0143 is fabricated using a 0.5 micron gate length GaAs PHEMT process. The process features full chip passivation for increased performance and reliability.
