Problems solved by technology

[0003] Traditional broadband configurable receivers often realize multi-mode, multi-frequency wireless signal transmission and reception through multi-channel switching. The design of the radio frequency receiver needs to add a band-pass pre-filter between the receiving antenna and the receiver, and due to The filter has high performance requirements and cannot be integrated, and in order to meet the requirements

Embodiment Construction

[0029] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0030] Such as figure 1 As shown, the broadband receiver chip 402 adopts a zero-IF receiver structure with quadrature down-conversion, and is divided into three parts: a radio frequency front-end module 100 , an analog baseband module 200 and a digital baseband 300 . The RF signal input terminal of the broadband receiver chip 402 is directly connected to the antenna without passing through a bandpass filter. The antenna directly inputs the received RF signal into the receiver, and the RF signal passes through the RF front end, analog baseband, and digital baseband in sequence. The RF front-end performs low-noise amplification and down-conversion of the input signal; the analog baseband performs low-pass filtering, amplification and oversampling on the analog signal; the digital baseband extracts and filters the oversampled digital code stream...

Abstract

The invention relates to a broadband radio frequency receiver and belongs to the technical field of wireless communication electronics. The broadband radio frequency receiver comprises a radio frequency front end module, an analog base band module and a digital baseband module; a zero-intermediate frequency receiver structure with orthogonal down conversion frequency is adopted; a radio frequency input signal sequentially passes through a low noise amplifier, a passive mixer, a trans-impedance amplifier, a low pass filter, a gain variable amplifier, an analog-digital converter, a decimation filter and a finite impulse response (FIR) filter; multiple radio frequency input signals within 50MHz to 6.3GHz can be processed by switching a low noise amplifier group and configuring local oscillation frequency, a sampling clock, filter bandwidth and the like; an external band-pass filter is not needed, so that the complexity of the system is reduced and the integration level is improved; a working frequency band is widened, and the flexibility and the reliability of the system are improved; in addition, the dynamic range is widened by double loop automatic grain control of a peak detection circuit and a power detection circuit. The broadband radio frequency receiver can be designed into an IP (Internet Protocol) core monolithic integration or can be in an external cascade.

Description

technical field [0001] The invention relates to a broadband radio frequency receiver, which belongs to the technical field of wireless communication electronics. Background technique [0002] With the rapid development of the current wireless communication electronic technology field, wireless communication has put forward higher and higher requirements for receiver integration, flexibility, communication standard compatibility, and engineering applicability. The competition in the wireless communication market is becoming more and more fierce. In order to achieve lower cost and smaller area, it is imperative to replace multiple receivers with one receiver to receive multiple radio frequency signals; at the same time, with the Internet of Things and handheld With the rapid development of mobile devices, the demand for a receiver capable of handling wireless signals of multiple communication protocols and communication standards is becoming stronger and stronger, and the requ...
