Description
Technical field
This utility model relates to communication device field, is specifically related to a kind of radio beacon transmitter.
Background technology
Radio beacon transmitter is i.e. at ground station or the radio-electronic equipment of offer own location information.In Aircraft Vectoring System, the frequency that one or several Land Navigation Installation specifies launches radio beacons signals, and the aircraft orientation relative to guidance station is measured or calculated to aircraft On-board Navigation equipment according to the beacon signal received so that it is it is more accurate to position.When the operating frequency of beacon is 283.5kHz to 325kHz, in the range of this, electromagnetic wavelength is 923 meters to 1058 meters, uses non-loaded vertical antenna to need 230.75 meters and could mate to 264.5 meters so that antenna structure is complicated and is difficult to.
Utility model content
This utility model provides a kind of radio beacon transmitter to solve above-mentioned technical problem, and it can make impedance matching between beacon and antenna, so that antenna maximal efficiency radiant output power on 283.5kHz to 325kHz.
This utility model is achieved through the following technical solutions:
A kind of radio beacon transmitter, including signal processing circuit, antenna and the power supply providing electric energy for signal processing circuit, described signal processing circuit includes the control module being sequentially connected, power amplifier module and the tuner being connected on power amplifier module, the outfan of described tuner is connected on antenna, described power supply includes that DC power supplier and AC/DC power module, described AC/DC power module include transformator, rectification circuit and the mu balanced circuit being sequentially connected.Antenna feed impedance changes with frequency change, if control module and antenna are directly connected to, when frequency changes, and impedance mismatch between control module and antenna, will reduce radiant power；And a part of power that the impedance mismatching between the frequency detuning of antenna and antenna and feeder line all can make feeder line send here is gone back by antenna-reflected, the mismatch of antenna also can reflect the connectivity port of transmission line and transmitter by transmission line, show as the mismatch between whole feedback system and transmitter control module, the a part of power making last stage of transmitter output is reflected back toward final circuit, affect the normal operating conditions of final stage, more seriously the power amplifier module of transmitter can be damaged, therefore between power amplifier module and antenna, connect tuner, impedance matching between beacon and antenna can be made, so that antenna maximal efficiency radiant output power on 283.5kHz to 325kHz.Radio beacon transmitter is visual plant, and power supply is its power supply, needs to use its reliability of mains-supplied the highest, the occasion that especially mountain area etc. often have a power failure.Use DC power supplier as backup battery module, improve the reliability of power supply, it is to avoid the puzzlement of mains failure.Civil power exports galvanic current source through transformator, rectification circuit and mu balanced circuit successively and provides electric energy for signal processing circuit.
As preferably, described tuner is additionally provided with lightning protection circuit on the connection end of antenna.Antenna is disposed in the outdoor, and is easily attacked by thunder and lightning, arranges lightning protection circuit on the tuner connection end with antenna, it is to avoid thunder and lightning is attacked.
Further, described lightning protection circuit includes the current-limiting resistance being serially connected between power supply and signal processing circuit and is connected to first Transient Suppression Diode at resistance two ends, the second Transient Suppression Diode, the negative electrode of described first Transient Suppression Diode is connected between resistance and power supply and plus earth, and the negative electrode of described second Transient Suppression Diode is connected between resistance and signal processing circuit and plus earth.Lightning protection circuit uses resistance to carry out current limliting, it is to avoid during thunder and lightning effect, the heavy current destruction to transmitter internal circuit.First Transient Suppression Diode is as prime thunder and lightning leadage circuit, and when thunder and lightning acts on antenna, its voltage instantaneous increases, and voltage increase makes the first Transient Suppression Diode conducting thus reaches the purpose that thunder and lightning is released；Second Transient Suppression Diode plays the purpose that secondary is released, and when thunder and lightning is not released complete by the even first Transient Suppression Diode, the second Transient Suppression Diode is released again, improves the reliability that thunder and lightning is released.Use this thunder and lightning leadage circuit, its simple in construction, with low cost.
As preferably, between described power supply and signal processing circuit, it is provided with power change-over switch.The power supply mode of power supply is switched over by power change-over switch.
As preferably, described DC power supplier is connected with AC/DC power module by charge-discharge control circuit.DC power supplier uses rechargable power supplies module; use AC/DC power module that it is powered; in charge and discharge process; the discharge and recharge of DC power supplier is managed by charge-discharge control circuit; avoid the phenomenons such as DC power supplier overcharges; protection DC power supplier, improves the life-span of DC power supplier.
This utility model compared with prior art, at least has such advantages as and beneficial effect:
1, this utility model in control module and connects tuner between manifesting, and can make impedance matching between beacon and antenna, so that antenna maximal efficiency radiant output power on 283.5kHz to 325kHz.
