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.
- 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
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
