PN 61221C-2

High Power Diplexer

61221C-2

PN 61221C 1


P/N 61221C-2 is a high power diplexer developed at RS Microwave for applications at the low end of the UHF frequency band. The unit employs innovative techniques in order to obtain optimum insertion loss and isolation performance otherwise unattainable using standard state-of-art techniques. Pseudoelliptic characteristics are obtained for both RX and TX channels by implementing some of the concepts that RS Microwave has recently published in the microwave literature on the generation of transmission zeros, while superior performance in terms of resonators quality factor and temperature stability is obtained by implementing RS Microwave patented composite resonator concept. The diplexer is manufactured according to RS Microwave quality standards to withstand the environmental conditions of military applications.
