The DPX2 is a mini-size diplexer series, designed for applications in satellite reception systems to combine or separate two different signal bands. For example, to combine or separate C band / Ku Band or Hi Band / Low Band.
Despite its small size it has exceptional performance such as a typical rejection of 40dB, a return loss of 14dB (typ.), a very even pass band and an insertion loss of less than 1dB (typ.).
Apart from the excellent electronic specifications, it boasts a high quality die-casting housing with high RFI shielding effectiveness.
In addition to the general models in the table below, the satellite-IF bands can be designed according to customer specifications.
