Embodiment Construction

[0066] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0067] The basic idea of ​​the present invention is to propose a microwave complementary duplexer, which is a three-port microwave passive device, including a band-pass channel and a band-stop channel. It is characterized in that: when a broadband signal is fed in from the common terminal, the output of the band-pass channel of the duplexer is a pass-band signal, while the output of the band-stop channel is a broadband signal and eliminates spectrum signals other than the pass-band signal. The bandpass channel of the duplexer is well matched in the passband, the stopband can be well matched outside the passband, and the common end is well matched in the full frequency band. The complementary duplexer can realize the spectrum separation or synthesis function in the microwave frequency band. It can be used to measure the spectral components of...

Abstract

The invention relates to a microwave complementation duplexer. The duplexer adopts a three-port microwave passive device, and comprises a bandpass channel and a band stop channel. The duplexer is characterized in that when a wide band signal is fed through a common port, the output signals of the bandpass channel of the duplexer belong to bandpass signals, and output signals of the band stop channel belong to spectrum signals of broadband signals other than bandpass signals. The bandpass channel of the duplexer is properly matched in a passband, a stop band can be properly matched outside the passband, and the common port can be properly matched in a full spectrum band. The complementation duplexer can realize a spectrum separation or synthesis method of a microwave frequency band. The complementation duplexer can be used for measuring a spectrum component in a designated frequency band of a broadband signal, such as the measurement of passive intermodulation. In addition, after duplexers serve basic modules are subjected to cascade connection, a multiplexer is formed. Finally, an absorbing mode filter can be realized after a stop band channel output terminal of the duplexer is connected with a matched load.

Description

technical field [0001] The invention relates to a microwave frequency band duplexer. Two channel signals of the duplex are completely complementary, that is, the broadband signal can be split into a passband signal and a broadband signal outside the passband when duplexed. Such as figure 1 shown. Background technique [0002] The traditional microwave duplexer synthesizes two signals of different frequencies or splits a broadband signal into two signals of different frequencies. The two-way signals are limited within a certain bandwidth range, and the one with the frequency band separation function can realize the complementary function in the true sense, that is, the transmission characteristics of the band-pass and band-stop channels are just a design method of the transmission function and reflection function of a filter function and products have not been reported. [0003] Although the design of the band-pass filter and the band-stop filter is a mature technology, th...
