About the RFSWITCH01 PCB

RFSWITCH01 is an open source PCB design by mlab-modules, published on GitHub under the GPL-3.0 license. It is a 2-layer board measuring 40.1 × 40.1 mm, with 41 components from 22 distinct parts.

Other key parts include the TPS22945DCKR, PE4259 and SPF5189Z. By type, the board carries 10 connectors, 10 capacitors, 6 inductors, 6 resistors, 4 ICs and 4 diodes.

It belongs with the rf & radio and robotics & motion designs in this gallery.

From the project

The module featuring two RF switches. Designed for radio transceivers with separate input and output.

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.
