The RF1630 is a single-pole, dual-throw (SPDT) switch which offers very low insertion loss along with excellent linearity performance. The RF1630 is ideal for UMTS and LTE handset applications. The RF1630 is controlled by a GPIO interface and resides in a compact 1.1 mm x 0.7 mm, 6-bump WLCSP, which allows for a small solution size with no need for external DC blocking capacitors in typical applications.
