PROES TRX-V.a RF Transceiver

PROES TRX-V.a is an RF transceiver for narrow band applications providing a fully bi-directional, secure RF communication network which is developed based on PROES patented technology to improve the quality and reliability of wireless communication links.

PROES patented solution (implemented in FPGA) makes the RF link more immune to the errors arising from burst noise, channel fading, and signal interference by improving the sensitivity of the system for non-satellite, long range communication applications. This cutting-edge technology allows us to communicate up to 21dB below the noise level (i.e., when the power of the informative received signal is 128 times weaker than the power of surrounding detectable noise).

In order to maximize the performance, the receive (Rx) and transmit (Tx) paths are completely separated in our hardware design. The received RF signal is down-converted by using a fully integrated RF receiver. To generate the output signal more accurately, a separate integrated modulator was used.

PROES TRX-V.a supports 169, 433, 868 and 915 MHz carrier frequencies of the ISM bands which is also adaptable to support 70 MHz up to 8 GHz, including licensed and unlicensed radio systems.

PROES user-friendly Graphical User Interface (GUI), provides you with full control of communication network via PCs
