The PE42821 is a HaRP™ technology-enhanced high power reflective SPDT RF switch designed for use in mobile radio, relay replacement and other high performance wireless applications. This switch is a pin-compatible faster switching version of the PE42820. It maintains high linearity and power handling from 100 MHz through 2.7 GHz. PE42821 also features low insertion loss and is offered in a 32-lead 5 × 5 mm QFN package. In addition, no external blocking capacitors are required if 0 VDC is present on the RF ports.
