Duplexers,Frequency Range 400-520 MHZ and 800 to 950 MHz
OPT HELLAS Duplexers are band reject type cavity filters which are designed for simultaneous Receiver/Transmitter operation through a single common antenna port. These Duplexers cover the typical frequency range from 66 MHz to 960 MHz. standard 6 cavity duplexers are available with excellent electrical Characteristics and Noise Suppression between the Transmitter and Receiver ranging from 60 to 90 db.
These Duplexers are ideal for 50 Ω Repeaters and Base Station applications where higher Power and compact dimensions are essential. The cavities are made from extruded Aluminum and the chassis from Passivated steel. The coil forms of the High Q helical resonators are made from Teflon to improve the Electrical Characteristics of the Filters.
