Abstract
The utility model discloses an integrated services digital network (ISDN) radio frequency front-end, which comprises an S-band low-noise amplifier, an L-band power amplifier, combiners and a power supply module. The S-band low-noise amplifier carries out low-noise amplification on received S-band radio frequency signals, the signals are then outputted to the first shunting port of the combiner one, and then outputted to the combiner two via one radio frequency cable connecting the combining port of the combiner one and the combining port of the combiner two, and the first shunting port of the combiner two outputs the S-band signals. L-band radio frequency signals received by the second shunting port of the combiner two are outputted to the combining port of the combiner one via the combining port of the combiner two, and then outputted to the L-band power amplifier via the second shunting port of the combiner one. The L-band power amplifier carries out power amplification on the inputted signals, and the signals are outputted. The one cable has receiving signals, sending signals and working voltage, thereby saving cost, facilitating connection by a worker and preventing fault operation.
Description
Technical field
This product relates to electronic communication field, relates in particular to low noise amplifier, power amplifier and closes the Integrated Service Digital Network radio-frequency front-end in the fields such as road.
Background technology
Triones navigation system is the satellite navigation system of the independent foundation of China, and the monopoly position of the United States, Russia at this broken in his succeeding in developing, and solved the no problem that has of Chinese autonomous satellite navigational system.Secondly, triones navigation system has the multi-usages such as number of satellite is few, investment is little, subscriber equipment is simply inexpensive, can realize certain area navigator fix, communication, can satisfy the requirement that navigator fix is transported in China land, sea, air.
Existing radio-frequency front-end is connected with multi-cable with user side, maloperation easily occurs.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, has realized that the sending and receiving of Big Dipper satellite signal and operating voltage share a transmission line, prevent the Integrated Service Digital Network radio-frequency front-end of faulty operation.
The purpose of this utility model is achieved in that
The Integrated Service Digital Network radio-frequency front-end, comprise S-band low noise amplifier, L-band power amplifier, combiner and power module, it is characterized in that: the S-band low noise amplifier carries out exporting to after low noise amplification first minute road port of combiner 1 to the radiofrequency signal of the S-band that receives, the radio-frequency cable that road port is connected that closes that closes road port and combiner 2 by combiner 1 exports combiner 2 to again, and first minute road port of combiner 2 exported the signal of S-band; The radiofrequency signal of the L-band that second minute road port of combiner 2 receives, the road port that closes that road port exports combiner 1 to that closes by combiner 2, second minute road port by combiner 1 exports the L-band power amplifier to again, and the L-band power amplifier carries out the laggard line output of power amplification to the signal of input.
The utility model compared with prior art has the following advantages:
The utility model has adopted the connected mode of a cable, and this technology has been beaten broken traditional connected mode fully, has both saved cost, and the connection of also being convenient to the staff prevents faulty operation.
