Integrated RF Analog/Digital Transceiver

SKU: TXRX

The TxRx is a plug-and-play module designed to establish an RF link between two points using fiber optic cable or free-space transmission. It features a compact design that integrates both transmitter and receiver functions, along with a 17 dB gain broadband RF amplifier on the transmitter side. The system offers strong immunity to interference, high bandwidth, low signal loss over long distances, low distortion, low power consumption, and high reliability, making it easy to deploy in a wide range of applications. The module operates by converting an input RF electrical signal into an optical signal using an electro-optical modulator coupled with a DFB laser in the transmitter. At the receiving end, the optical signal is converted back into an RF signal through a high-linearity photodiode integrated with a low-noise amplifier. Together, the transmitter and receiver form a transceiver that provides a transparent data transmission channel. Bidirectional RF communication over a single fiber link can be achieved using a pair of cable adapters incorporating fiber optic circulators. A wall-pluggable power supply is included for ease of use. The unit requires mounting on a heat sink base.
The TxRx modules are well suited for applications such as telecommunications, satellite communications, radio telescopes, distributed antenna systems, audio/video broadcasting, and timing synchronization. For example, point-to-point antennas can be connected over distances ranging from several meters to many kilometers via fiber; base stations can link to remote sector antennas; and satellite antennas can be connected to remote sites using RF-over-fiber solutions.
