Description

Using advanced switching technologies, the GSR1351S is a single pole dual throw (SPDT) high power switch in a low cost miniature 1.0 mm × 1.0 mm package. The GSR1351S is ideally suited for applications where high power, low insertion loss and small size are required. Typical applications are for handset systems that connect separate transmit and receive functions to a common antenna, as well as other related handset and general purpose applications. This part can be used in all systems operating up to 7.2 GHz required high power at low control voltage.
