Duplexers target communications applications

Duplexers
Euroquartz has launched a range of duplexers that enable simultaneous transmit and receive from a single antenna in communications applications based on operational frequency and utility.
Enhancing the company's crystal filter offering, the duplexers are three-port devices comprising a combination of transmit and receive filters with a common antenna port.
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 50ohms impedance, 50W maximum power, standing wave ratio (SWR) less than 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 50ohms impedance, 40W maximum power, SWR less than 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 60C.
