Abstract
A radio frequency sampling receiver of the utility model relates to the electronic communication field, and aims to solve the technical problems that a conventional L-wave band receiver is poorer in processing flexibility and is larger in volume, and the signal of the conventional L-wave band receiver is easy to intercept, etc. The radio frequency sampling receiver of the utility model is characterized in that the input end of an amplitude limiter (1) receives an input signal, and the output port is orderly connected with a low noise amplifier (2), a broad band filter (3), an amplifier 1 (4), a low pass filter 1 (5), a temperature compensated attenuator (6), an attenuator (7), an amplifier 2 (8), a low pass filter 2 (9) and a digital signal processing unit (10).
Description
Technical field
The utility model relates to electronic communication field, particularly a kind of receiver of radio frequency sampling for the L-band receiver.
Background technology
Present L-band receiver has all adopted digitized processing, but adopts the few of radio frequency sampling technology, and there are the following problems simultaneously:
1. the processing flexibility of receiver is poor;
2. signal is is easily intercepted and captured;
3. volume is larger.
Summary of the invention
The utility model is intended to solve existing L-band receiver and exists and process that flexibility is poor, signal is is easily intercepted and captured and the technical problem such as volume is larger, the radio frequency sampling receiver that process to provide a kind of that flexibility is good, signal is difficult for being intercepted and captured and volume is little.
The purpose of this utility model is achieved through the following technical solutions.
Radio frequency sampling receiver of the present utility model, the input of amplitude limiter 1 receives input signal, and its output port connects low noise amplifier 2, broadband filter 3, amplifier 1, low pass filter 1, temperature compensation attenuator 6, attenuator 7, amplifier 28, low pass filter 29 and digital signal processing unit 10 in turn.
Radio frequency sampling receiver of the present utility model, the operating frequency of wherein said broadband filter 3 are 995-1125MHz.
The beneficial effect of the utility model radio frequency sampling receiver: the processing flexibility is good, signal is difficult for being intercepted and captured and volume is little.

The number in the figure explanation:
1 amplitude limiter, 2 low noise amplifiers, 3 broadband filters, 4 amplifiers one, 5 low pass filters one, 6 temperature compensation attenuators, 7 attenuators, 8 amplifiers two, 9 low pass filters two, 10 digital signal processing units
Embodiment
The utility model detailed construction, application principle, effect and effect,, with reference to accompanying drawing 1, be explained by following execution mode.
Consult shown in Figure 1, radio frequency sampling receiver of the present utility model, the input of amplitude limiter 1 receives input signal, and its output port connects low noise amplifier 2, broadband filter 3, amplifier 1, low pass filter 1, temperature compensation attenuator 6, attenuator 7, amplifier 28, low pass filter 29 and digital signal processing unit 10 in turn.The operating frequency of broadband filter 3 is 995-1125MHz.
Radio frequency sampling receiver of the present utility model, by the signal process amplitude limiter that antenna reception arrives, amplifier, after filter, then carry out filtering, amplify, filtering, to the scope that A/D receives, is carried out the processing (FPGA carries out real-time signal to be processed) of total digitalization finally; Can find out from schematic diagram, whole passage is a general passage, has the characteristics of quick response; Digital Signal Processing also has this fast characteristics of response, and bandwidth determines jointly by analog filter and digital filter, is mainly that Digital Signal Processing can be completed the full bandwidth (≤500MHz) signal handling capacity of code check.
Radio frequency sampling receiver of the present utility model, the reception signal of receiver, through prime amplitude limit, low noise amplifier, carry out the broadband rf signal of total digitalization and process after wideband filtered.Passage is the passage of a high-speed response, and follow-up digital processing can be adjusted bandwidth as required, and is the widest up to 500MHz; Due to the high speed of passage and follow-up real time signal processing, the system that guaranteed can be operated on the mode of operation of high-speed frequency-hopping.
Radio frequency sampling receiver of the present utility model, the fast jumping mode of operation (despreading, demodulation) of any mode of bandwidth that can Shi Xian＜=500M, and also time delay is little, and real-time.
