Abstract
The utility model discloses a minitype receiving module; the minitype receiving module comprises a coupler, an amplitude limiting module and a switch selecting module which are arranged in the same chamber and are sequentially cascaded; the chamber is also internally provided with an attenuator and an amplifier; and the switch selecting module is used for selecting the attenuator and the amplifier to work, and is used for carrying out radio frequency output. According to the minitype receiving module, all the modules are integrated into one chamber, so that the minitype receiving module is small in volume, low in noise, small in all-temperature range output gain fluctuation, rapid in switching speed, convenient to use, high in reliability, long in service life and the like; and a great deal of microwave components are integrated into a whole, so that the purchase types of the product can be reduced, the complexity of a system is reduced, and the efficiency is improved.
Description
Technical field
The utility model relates to a kind of circuit module, relates in particular to a kind of miniaturization receiver module.
Background technology
Receiver module is used for quick frequency conversion system, can be widely used in fields such as frequency hopping communications, radar, electronic warfare.At present, domestic similar products adopt microwave component to build, and each parts all adopts the separate chambers structure, cause the layout complicacy and need to use a large amount of cables to connect.Final finished volume big (150mm*120mm*20mm), volume is heavy, uses inconvenience, poor reliability, maintenance cost is high.
Summary of the invention
The purpose of the utility model just is that providing a kind of addresses the above problem, and integrated a plurality of modules realize miniaturization Design, improve product applicability, reduce small product size, improve the miniaturization receiver module of product reliability and life of product.
To achieve these goals; The technical scheme that the utility model adopts is such: a kind of miniaturization receiver module; Comprise the coupler, amplitude limit module, the switch selection module that are positioned at same chamber and cascade successively; Also be provided with an attenuator and an amplifier in the chamber, said switch selects module to select attenuator and amplifier work, and carries out radio frequency output.
As preferably: each intermodule adopts 50 ohm transmission line to connect.
As preferably: the input of coupler and switch select the output of module to stretch out chamber, and are connected with SMA plug-in seat.
As preferably: the parallel line type coupler that said coupler designs for microstrip circuit, attenuator are the monolithic fixed attenuator; Amplifier is the monolithic low noise amplifier.
Compared with prior art; The advantage of the utility model is: each module is fully integrated in the chamber; Volume is little, noise is low, total temperature scope output gain fluctuation is little, switching speed is fast, easy to use, reliability is high, the life-span is long etc., owing to a large amount of microwave components are become one, has reduced the buying kind of product; Reduce the complexity of system, improved efficient.
Description of drawings
Fig. 1 is the circuit theory diagrams of the utility model.
Among the figure: 1, coupler; 2, amplitude limit module; 3, switch is selected module; 4, attenuator; 5, amplifier.
Embodiment
To combine accompanying drawing that the utility model is described further below.
Embodiment 1: referring to Fig. 1, a kind of miniaturization receiver module comprises the coupler 1, amplitude limit module 2, the switch selection module 3 that are positioned at same chamber and cascade successively; Also be provided with an attenuator 4 and an amplifier 5 in the chamber, said switch selects module 3 to select attenuator 4 and amplifier 5 work, and carries out radio frequency output; Each intermodule adopts 50 ohm transmission line to connect, and the input of coupler 1 and switch select the output of module 3 to stretch out chamber, and are connected with SMA plug-in seat; In the present embodiment; The parallel line type coupler that said coupler 1 designs for microstrip circuit, amplitude limit module 2 is processed by three kinds of amplitude limit degree diodes, and attenuator 4 is the monolithic fixed attenuator; Amplifier 5 is the monolithic low noise amplifier.
Design selects each module as above for use during the utility model, and above-mentioned module is high integration; Volume is little, optimizes the arrangement of above-mentioned each module again, and it is fully integrated in the chamber; It is bulky to avoid adopting a plurality of chambers to cause; Amplitude limiter is processed by three kinds of amplitude limit degree diodes, can adapt to the application of power magnitude restriction on a large scale, and input signal is selected module 3 through coupler 1, amplitude limit module 2, switch successively; Thereby select to amplify or decay, play the amplification of low noise small-signal, dynamic range expanded effect.
Each intermodule adopts 50 ohm transmission line to connect.Avoided the use of cable, the input of coupler 1 and switch select the output of module 3 to stretch out chamber, and are connected with SMA plug-in seat, have improved the convenience that the user uses, and simultaneously, improved the reliability of products height, have prolonged life of product.
