Wireless transmitter having a modified translation loop architecture

摘要：

A transmitter for a wireless handset having a modified translation loop architecture. The transmitter includes a VCO that generates a modulated transmit signal having a frequency fTx, and a modulated signal source that generates a modulated LO signal with a frequency fLO. A mixer mixes the transmit signal with the LO signal to produce an IF signal having a frequency fIF. A first divider divides the LO signal frequency fLO by an integer M to generate a first comparison signal having a frequency fCF. A second divider divides the IF signal frequency fIF, after it is multiplied by an integer K, by an integer N to generate a second comparison signal having a frequency fCF. The transmit and LO signal frequencies have the relationship f Tx = f LO ⁢ KM ± N M . A phase detector coupled to the first and second comparison signals compares the phases of the signals and outputs a control voltage to the VCO proportional to any phase differences between the signals.

摘要（中）：

一种用于具有修改的平移环结构的无线手机的发射机。发射机包括产生具有频率f Tx的调制的发射信号的VCO和产生具有频率为LO LO的调制LO信号的调制信号源。混合器将发送信号与LO信号混合以产生具有频率f IF IF的IF信号。第一分频器将LO信号频率f LO LO分频整数M以产生具有频率f CF1的第一比较信号。第二分频器将IF信号频率f IF IF在乘以整数K之后除以整数N，以产生具有频率f CF1的第二比较信号。发送和LO信号频率具有关系 $f> Tx=耦合到第一和第二比较信号的相位检测器比较信号的相位并输出控制 VCO的电压与信号之间的任何相位差成正比。公开/授权文献 US20030139148A1
