DuplFour 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.
