News Release from:
Euroquartz Limited
22 October 2012
Euroquartz has today revealed the introduction of a new range of duplexers enabling simultaneous transmit and receive from a single antenna. Enhancing the company's crystal filter offering, 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 88MHz duplexers are available in 5 and 2,3MHz split versions. Both feature 50Ω impedance, 50W maximum power, standing wave ratio <1.5 and frequency stability of 9ppm/°C. Connector is Pi-female and dimensions are 270 x 156 x 33mm, weight 1.4kg.
DU-9060-G GSM and DU-7062-T Tetra duplexers feature 50Ω impedance, 40W maximum power, SWR <1.5 and frequency stability of 10ppm/°C. Connector for these models is N-female and dimensions are 180 x 156 x 33mm, weight 0.9kg.
Operating temperature range for all duplexers is -30 to +60°C.
