Description
Technical field
The utility model relates to a kind of intelligent terminal radio frequency antenna matching circuit.
Background technology
Current server system is to CPU, the reliability requirement of internal storage data read-write is more and more higher, CPU, internal memory is constantly handling up the computational data of automatic network and hard disk, a lot of computational datas are core critical data, once lose irrecoverable, there is real-time, therefore the service condition of server system has been proposed to very large challenge, in order to guarantee the reliable of internal storage data read-write, can not power down in system power supply in service, it is abnormal etc. that the power conversion chip of server master board inside can not have, the power supply of server system at present designs intelligent As soon as possible Promising Policy redundancy demand, but ought and then bring such problem, that is exactly the rising of thing followed volume and cost, the radiating requirements part of power supply also can increase, when while redundant power or AC power supplies power down, will cause a large amount of loss of internal storage data, the reliability that reads and writes data need to fundamentally guarantee.
Be badly in need of at present a kind of intelligent terminal radio frequency antenna matching circuit, to suppress undesired signal, guarantee the correct input of data.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of intelligent terminal radio frequency antenna matching circuit is provided, and effectively Inhibitory signal disturbs, by a plurality of filter capacitors and inductance are set, make input signal standard, accurately more, for the normal work of intelligent terminal provides safeguard.
The purpose of this utility model is achieved through the following technical solutions: a kind of intelligent terminal radio frequency antenna matching circuit, it comprises resistance R 1, capacitor C 1 and C2, inductance L 1, the GPS input port of intelligent terminal is connected with GPS receiving antenna with inductance L 1 by capacitor C 1 successively, portable data input port is connected with portable data receiving antenna by capacitor C 2, and TX-RBIAS port is by resistance R 1 ground connection.
Described inductance L 1 is also connected with one end of inductance L 2 with the points of common connection of GPS receiving antenna, the other end ground connection of inductance L 2.
The beneficial effects of the utility model are: be provided with a plurality of filter capacitors and inductance, the signal that makes input is standard, accurately more, for the normal work of intelligent terminal provides guarantee.
