摘要： For providing a module for use of a mobile communication terminal, being small in sizes and high in reliability, and enabling with plural numbers of bands, and also a mobile communication terminal with using the same therein, canceling is conducted on transmission signal and/or noises of reception band on reception side with using a feed forward technology, for maintaining a degree of suppression of the transmission signal and/or the noises of reception band on the reception side. In this case, for achieving the cancellation of wide band signals from the transmission signal to the reception band, a delay adjusting function is used, in addition to gain and phase adjusting functions. Also, for conducting stable canceling of jamming signals, controls are conducted on the gain, the phase and the delay of a loop with using a reception SN and/or a CQI signal, etc.Further, for achieving low power consumption, a feed forward loop can be made ON/OFF depending on a level of the transmission signal.

When the send and received signals of the first modulation method are input, the send signal and the received signal of the first modulation method are wave-separated and output by the duplexer. When the received signal of the first modulation method is input, the send signal and the received signal of the first modulation method are wave-separated and output by the duplexer, and the send signal of the second modulation method is filtered by the filter.

摘要： A tunable filter in a tunable DPX module has frequency characteristics, and thus needs to be controlled with high accuracy so as to simultaneously cancel a transmission signal and noise in a reception band on a transmission side. For this reason, a canceller includes a filter having the same frequency characteristic as that of a tunable filter, and a structure having functions of compensating for an amplitude, a phase, and a delay. And, two lines of the cancellers are used to individually cancel a leak component of a transmission signal and a leak component of thermal noise in a reception band. In order to save the power consumption of the amplifier, a coupler is loosely coupled, and a combiner is tightly coupled. Further, in order to suppress the influence on a reception system due to the tough coupling, the combiner uses the amplifier for in-phase inputs.
摘要翻译：可调DPX模块中的可调滤波器具有频率特性，因此需要高精度地控制，以便同时消除发送侧的接收频带中的发送信号和噪声。因此，消除器包括具有与可调谐滤波器相同的频率特性的滤波器，以及具有补偿振幅，相位和延迟的功能的结构。并且，使用两行消除器单独地消除接收频带中的发送信号的泄漏分量和热噪声的泄漏分量。为了节省放大器的功耗，耦合器松耦合，组合器紧密耦合。此外，为了抑制由于强耦合对接收系统的影响，组合器使用用于同相输入的放大器。
