Key technology solutions and important functions:





A. ultra high frequency wideband interference technology





The realization of the core function of the technology (single frequency band) consists of two functional IC and its peripheral matching circuit.





TXVCO (commonly known as interference source): VCO is a synthetic component, in fact a voltage - frequency conversion device, which converts the variation of the phase voltage signal output by the phase detector to the change of frequency, thus producing the desired interference source.





PA (power amplifier): the internal PA is composed of power drive, power amplification, detection and other parts, so the peripheral PA is added to match high frequency rectifier, power detection and error voltage amplification.









The key point of realizing the function of the TX-101E-6A mobile phone shielding device is to break through the following two aspects:



(1) broadband, high power output: to improve the broadband power gain, the power stability control after the increase of the gain, the intra band stability and the control of the band out of band, the control of the outshoot index, the wide frequency output Bobbi index (some indexes are repeatedly adjusted before the design of the R & D scheme, the normal production, the product quality. " After stability).



(2) interference between multiple systems: in the smaller space of the shielding machine, there are 6 systems launching, CDMA, GSM, DCS/PHS and 3G.4G.
