在無線通信系統(tǒng)全面進(jìn)入3G并開始邁向 4G的過程中,使用數(shù)字預(yù)失真技術(shù)(Digital Pre-distortion,以下簡稱DPD)對發(fā)射機(jī)的功放進(jìn)行線性化是一門關(guān)鍵技術(shù)。功率放大器是通信系統(tǒng)中影響系統(tǒng)性能和覆蓋范圍的關(guān)鍵部件,非線性是功放的固有特性。非線性會引起頻譜增長(spectral re-growth),從而造成鄰道干擾,使帶外雜散達(dá)不到協(xié)議標(biāo)準(zhǔn)規(guī)定的要求。非線性也會造成帶內(nèi)失真,帶來系統(tǒng)誤碼率增大的問題。

Demonstration circuit 1562A is an engineering toolto design and evaluate the LTC699X-X family ofTimerBlox circuits. The center section of the boardcontains a pre-configured TimerBlox function.DC1562A comes in twelve timing function variationsas outlined in Table 1.Surrounding the center board is a ”playground”prototyping area. The prototyping area has padsfor Dip-8, S8, MS8, or S6 packages with breadboarding connections to each pin and two convenientpower buses and ground bus surrounding theentire area. This area is for conditioning signals tocontrol the timer function and for adding loads controlled in time.
