Our 2" base station duplexers are ideal for compact high isolation installations. These filters are designed for the combination of two frequencies that require extra isolation, or they can be used as efficient preselectors. Selectivity can be determined by the field adjustable capacitors. Each cavity is temperature compensated for operation between -40ºC to +60 ºC. Each cavity has a gold Alodine finish, silver-plated loops, and silver-plated tuning rods.

Our Control Station Combiners (CSC) is an ideal solution to reduce the number of antennas required on a communications site by maintaining a high radio-to-radio isolation at all times. It can significantly reduce tower clutter and loading, and simplify cabling installation at control center facilities. This product provides frequency-agile operation across a frequency range from 746 up to 869 MHz covering the public safety bands 700 and 800. This combiner has the possibilities to be connected to two antennas TX and RX. In case of only one antenna is used for TX and RX, an external duplexer is required. This unit is also available in 8, 12, 16 and 32 ports configuration. DOWNLOAD PDF

The RFoF link has excellent gain flatness and can be configured to have 0.5dB gain tracking between different links.
- Noise Figure 6 dB with LNA
- Impedance of 50 Ohm. 75 Ohm is optional with similar VSWR, by using SMA/BNC adaptor.
- Gain variation S21 (fo) of ±1 dB for 90° C variation
- Better linearity, excellent gain flatness, and Tx, Rx and Link gain control
- Real-time diagnostic of deployed links through GUI installed on the PC
