Antenna duplexers

13 April 2011 Telecoms, Datacoms, Wireless, IoT

The new duplexers are three-port devices comprising a combination of transmit and receive filters with a common antenna port.

Duplexers are designed for a variety of communications applications based on operational frequency and utility. For example, mobile duplexers are designed to handle low power and are very compact in size. Conversely, base station duplexers are designed to handle higher base radio power and are generally designed for mounting in standard equipment racks.

Four models are available in the range: DU-462-L 66 to 88 MHz duplexers are available in 5 and 2,3 MHz split versions. Both feature 50 Ω impedance, 50 W maximum power, standing wave ratio (SWR) <1,5 and frequency stability of 9 ppm/°C. The connector is Pi-female and dimensions of the 1,4 kg device are 270 x 156 x 33 mm. The DU-9060-G GSM and DU-7062-T Tetra duplexers feature 50 Ω impedance, 40 W maximum power, SWR <1,5 and frequency stability of 10 ppm/°C. The connector for these 0,9 kg models is N-female and dimensions are 180 x 156 x 33 mm. Operating temperature range for all duplexers is -30°C to +60°C.
