Embodiment

[0061] like figure 1 As shown in the circuit schematic diagram of the embodiment of the present invention, the present invention provides an N77 bandpass filter based on an IPD process, including a first port 1, a second port 2, a bandpass filter circuit and a base layer. The base layer is used to carry the first port 1 , the second port 2 and the bandpass filter. The band-pass filter circuit includes a series circuit and a plurality of parallel circuits, and is used to block the signal of the input signal outside the frequency band. The first port 1 is connected to one end of the series circuit for receiving an input signal. The second port 2 is connected to the other end of the series circuit, and is used for outputting a signal in the frequency band range after being processed by the band-pass filter circuit.

[0062] In the embodiment of the present invention, the series circuit includes a plurality of series capacitors connected in sequence, the series capacitor include...

Abstract

The invention relates to the field of wireless communication systems, in particular to an N77 band-pass filter based on an IPD process, which comprises a first port, a second port, a band-pass filter circuit and a substrate layer, the substrate layer is used for bearing the first port, the second port and the band-pass filter, the band-pass filter circuit comprises a series circuit and a plurality of parallel circuits, the band-pass filter circuit is used for blocking a signal outside a frequency band range of an input signal, the first port is connected with one end of the series circuit and used for receiving the input signal, and the second port is connected with the other end of the series circuit and used for outputting a signal in the frequency band range after being processed by the band-pass filter circuit. The beneficial effects are that the size of the band-pass filter is reduced by using the IPD technology, miniaturization of the whole microwave communication system is facilitated, and the out-of-band attenuation performance of the IPD filter is improved through circuit design.

Description

technical field [0001] The invention relates to the field of wireless communication systems, in particular to an N77 bandpass filter based on an IPD process. Background technique [0002] In recent years, with the rapid development of electronic and microwave communication systems, it is inevitable that there is an increasing demand for components with smaller size, higher integration, low cost, and better performance. [0003] Bandpass filters are one of the largest and most important components of an RF front-end. Most conventional bandpass filters use quarter wavelength transmission lines or discrete components. However, such bandpass filters are bulky and off-chip, especially at low frequencies, occupying a large amount of space, posing a major obstacle to the miniaturization and integration of microwave communication systems. [0004] Integrated passive device (IPD) technology was developed to meet the ever-increasing size and cost demands of microwave communication s...
