摘要： A method and apparatus can cut back power in a simultaneous dual frequency band call. The method may operate a dual frequency band transmit device. The method may include determining if a transmit frequency in a first frequency band from the device combined with a transmit frequency in a second frequency band from the device causes receiver desensitization at the device. The method may include determining if the transmit power in the first frequency band is above a threshold power. The method may include reducing maximum transmit power in the second frequency band by an amount proportional to transmit power in the first frequency band and transmit signal bandwidth in the second frequency band in only the portion of the second frequency band where a resultant frequency component can cause desensitization.

摘要： A method for reducing current drain in a communication device includes a step of determining when the communication device is transmitting. A next step includes lowering the current level to the receiver when communication device is not transmitting. A next step includes raising the current level to the receiver when communication device is transmitting. Changing the current level alters the linearity of the receiver. As a result, the communication device reduces power consumption while operating in a traffic channel. The system is applicable to full duplex systems such as code division multiple access (CDMA) systems.

摘要： A directional coupler (103) for radio equipment couples a radio frequency signal from an input of a microstrip transmission line (309) to an output and provides a directionally coupled output via a stripline microstrip (311). Open circuit microstrip transmission line stubs (313 and 315) are tuned to a quarter wavelength of the third harmonic of the radio frequency to provide third harmonic rejection within the directional coupler.

摘要： Microprocessor (MPU) controlled voltage controlled oscillator (VCO) linearization circuitry locks the VCO at desired low, center and high frequencies (F.sub.1, F.sub.c and F.sub.h) and measures the magnitudes of the corresponding control voltages (V.sub.1, V.sub.c and V.sub.h). Next, the VCO is swept at a nominal clock frequency to determine the times (T.sub.1, T.sub.2 and T.sub.h) that the control voltages (V.sub.1, V.sub.c and V.sub.h) occur during the sweep cycle. The control voltage of the VCO is then swept at a first and then a second rate during a sweep cycle to assure that the center frequency (F.sub.c) of the VCO occurs at the time (T.sub.c) midpoint of the sweep cycle. As a result, each VCO frequency can be determined by MPU monitoring according to the time that the VCO frequency occurs during the sweep cycle. This circuitry is useful in spectrum analyzers for indirectly determining the otherwise unknown frequency of a received signal.
摘要翻译：微处理器（MPU）控制的压控振荡器（VCO）线性化电路将VCO锁定在期望的低，中心和高频（F1，Fc和Fh），并测量相应的控制电压（V1，Vc和Vh）的幅度。接下来，以标称时钟频率扫描VCO，以确定扫描周期期间发生控制电压（V1，Vc和Vh）的时间（T1，T2和Th）。然后，在扫描周期期间，VCO的控制电压以第一速率和第二速率扫描，以确保在扫描周期的时间（Tc）中点发生VCO的中心频率（Fc）。结果，可以根据在扫频周期期间VCO频率发生的时间的MPU监视来确定每个VCO频率。该电路在用于间接确定接收信号的未知频率的频谱分析仪中是有用的。

摘要： An additional mixer is included in the feedback loop of a PLL which can be one of the local oscillators of a dual conversion system. A fine tuning frequency synthesizer is coupled to an input of the additional mixer for providing fine frequency control of the PLL. The fine tuning frequency synthesizer can include an additional phase locked loop. Also, a feedback signal for suppressing noise created by another local oscillator can also be applied to the additional mixer.
