RX2050 receiver is a device intended for installation in mobile devices. It ensures reception of RF signals from transceivers operating in 25 MHz to 146 MHz fixed frequency band. Transceiver modulation in 30 MHz to 108 MHz band meets the requirements of STANAG 4204 standard. In other bands, the receiver is capable of receiving signals from RF2050 or other transceivers that are compatible with the RF2050 in terms of modulation at these frequencies. The RX2050 receiver also receives signals in frequency hopping mode and it is fully compatible with the RF2050 and RF20 transceiver modes. The receiver includes an effective co-site filter that allows simultaneous operation of the RX2050 receiver with RF2050 transceivers in a single vehicle in 30 MHz to 90 MHz operating band. The condition of compatible operation is the distance between recommended vehicle antenna types of at least 1.5 m and receiving and transmitting frequencies differing by at least 10 %. The RX2050 receiver is not designed for data transmission.
