Typical Application

The 4-channel auto-tuned combiner ARF8014-xx is used in TDMA DMR channel selective station. It consists of very narrow band high Q cavity resonator filters tuned by mean of stepper motors controlled by a frequency synthesizer.
The combiner is tuned through IP/Ethernet interface and locally using a USB interface.
An easy way for BS extension is to connect a combiner to another combiner in star node, increasing the BS capacity up to 8 channels.
The output can be connected to an optional pass-reject or duplexer filter for 2-way operation.
The combiner features low loss and low intermodulation and incorporates a monitoring board.
