Ebook: Triplexer For Wideband Varactor Frequency

This report describes a triplexer for a third harmonic varactor multiplier. Designed to cover the maximum bandwidth, that is one for
which the third and fourth harmonic bands are contiguous, the triplexer and its associated harmonic rejection filters embody a wide range of microwave stripline filter design techniques.
These include quarter wave stub, parallel-coupled and reentrant type resonators for bandstop filters , and inter digital and digital elliptic - type construction for bandpass filters.
The triplexer consists of two diplexers composed of singly-terminated pseudo-complementary bandstop and bandpass filters with Chebyshev response. Test results on this device with respect to its triplexing function (excluding harmonic generation tests with a varactor) are given.
