Product Summary
The SW-425TR is a Cellular T/R and Antenna Changeover Switch. The SW-425TR is a GaAs monolithic switch in a low cost SOT-26 surface mount plastic package. The SW-425TR is ideally suited for applications where very low power consumption (<10μA@5V), low intermediation 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 SW-425TR can be used as a conventional T/R switch or as an antenna diversity switch. The SW-425TR 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.
