Description
The present invention relates to a kind of end product of mobile communication, but more particularly relate to a kind of modular mobile telephone of the independent assortment that can change with the change of network.
As everyone knows, general mobile phone all is to be made of mobile phone main body and battery two parts, that is to say, general mobile phone can only be divided into main body and two modules of battery, wherein has only the battery module can dismounting and replacing.Though some mobile phone can be changed shell voluntarily by the user, existing various mobile phones all can not make user's replacing assembly relevant with network or function.And along with the development of mobile communication technology, mobile communication network and way to manage thereof are also constantly changing, and the cycle of this variation is shorter and shorter, speed is more and more faster, and this variation will directly cause the mobile phone of existing fixed component formula can't adapt to the variation of network or network managing mode and fall behind technically or be eliminated.Can infer, a mobile phone of having bought 2 years probably can not use present The application of new technique, maybe can't adapt to the change of network managing mode and causes The above results.And the user uses present new technology if desired, then must upgrade complete machine, and this was both uneconomical concerning domestic consumer, and was also unrealistic.In addition, existing fixed component formula mobile phone also can't be used as carphone etc.This shows, develop a kind of modular, but the mobile phone of independent assortment is imperative.Do not see the report of relevant module combined type mobile phone up to now as yet.
The present invention makes at the problems referred to above, its purpose is to provide a kind of functional module that mobile phone is divided into several dismantled and assembled replacings, can adapt to new network managing mode by changing module, but or possess the modular mobile telephone of the independent assortment of new function.
For achieving the above object, but the invention provides a kind of modular mobile telephone of independent assortment, this mobile phone is that the mobile phone complete machine is divided into radio frequency (RF), man-machine interface (OP) and three modules that can change of power supply, makes the user to adapt to different networks or standard by the module of changing wherein.
Described radio frequency (RF) module 1 comprises GSM standard module, DECT standard module, CDMA standard module, also can be the module of other standard.
Described man-machine interface (OP) module 2 can be only can caller's machine interface module, also can be the human-computer interface module that has clock and alarm clock function, sound-recording function and set up the RS232 serial ports.
Described power module 3 can be the common power module, also can be the intelligent electric source module of built-in super low-power consumption microprocessor (MCU).
Described radio frequency (RF) module 1 is made of receiving circuit 11, radiating circuit 12 and control circuit 13, and wherein receiving circuit 11 is connected in sequence by antenna, band pass filter J200, front end integrated circuit H200, intermediate-frequency filter J201, intermediate frequency integrated circuit H500; Radiating circuit 12 is connected in sequence by signal processor C5510, intermediate frequency integrated circuit H500, voltage controlled oscillator G300, power amplifier A400, filter Z400, duplexer ANTSW and antenna; Control circuit 13 is made up of radio circuit and the intermediate-frequency filter J201 that band pass filter J200, front end integrated circuit H200 and peripheral components thereof constitute.
Described various man-machine interface (OP) module 2 is equipped with a, b, three groups of interfaces of c, and wherein a interface is connected with power module 3; The b interface is connected with radio frequency (RF) module 1; The connection of c interface is sent/receiver multiplexer and keyboard multiplexer.

zSignal amplifies after lower frequency changer circuit becomes 71MH
zFirst intermediate-freuqncy signal.Downconversion process is to be realized by received signal and oscillation signals according mixing, promptly produces than the high 71MH of received signal by logical circuit control local-oscillator circuit
zLocal oscillation frequency, this local oscillation frequency and received signal mixing just in time obtain 71MH
zFirst intermediate-freuqncy signal.At the front-end circuit radiating portion, emission sampled signal (TXIN) becomes the bimodulus form to send into from 8,9 pin of H200 by after the filtering from the single mode formal transformation, sends into from 17,18 pin of H200 after the emission oscillation signals according converts bimodulus to by single mode.The mixing in H200 of this two signal produces 117MH
zEmission medium-frequency sampled signal (TXIFA, TXIFB), deliver to 10,11 pin of H500, in H500 and 117MH
zSignal by phase discriminator PHD) carry out phase demodulation, lock tranmitting frequency by the requirement of logical circuit.
