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.
Key Features and Specifications
- Contains two PE4259 RF switches from Peregrine Semiconductor
- Operating voltage: 1.8V to 3.3V
- Maximum operating frequency: 3GHz
- Low insertion loss (0.35 dB @ 1 Ghz, 0.5 dB @ 2 GHz)
- Operating temperature range: -40°C to 85°C
- Four MCX connectors for connection with the radio and two antennas
- Includes a SAW filter and LNA amplifier at the transceiver input
Applications
The RFSWITCH01 module can be used in a variety of applications where MIMO 2x2 support is required for a radio transceiver. This includes, but is not limited to:
- Drone communication systems
- Wireless data transmission systems
- Radio communication systems in robotics

Questions
How big is the RFSWITCH01 PCB?
It measures 40.1 × 40.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the RFSWITCH01 use?
45 parts, built around the PE4259-63. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the RFSWITCH01 KiCad files?
From the mlab-modules/RFSWITCH01 repository on GitHub, at the commit this page was made from: the board is hw/sch_pcb/RFSWITCH01.kicad_pcb and its schematic hw/sch_pcb/RFSWITCH01.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the RFSWITCH01 design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
