RFSWITCH01 - RF switch

Introduction

The RFSWITCH01 is an MLAB module that incorporates a pair of RF switches, specifically the PE4259. from Peregrine Semiconductor. This module is designed to connect to a radio transceiver that has separate radio input and output. Thanks to the use of two switches, the module allows connecting two antennas. The individual switches are controlled by a simple digital input signal. With RFSWITCH01, a transceiver can work with the support of MIMO 2x2. The module is typically assembled for frequencies of 433MHz and 868MHz.
