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.

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： A tunable filter has an out-of-band signal suppression amount of 30 dB that is smaller than 50 dB, the suppression amount of a typical duplexer. Thus, a canceller having a suppression amount of about 20 dB is necessary (particularly, a method is provided to obtain a suppression amount over a wide band without being adversely affected by the group delay characteristics and frequency characteristics of an amplifier included in a canceller). Delay devices corresponding to the group delay of the amplifier are disposed on the signal path of the tunable filter. The canceller includes a matching circuit that adjusts an amplitude, a phase, and a delay, a wide-band amplifier that has small amplitude fluctuations and small phase fluctuations over the frequency bands of a transmission signal and a reception signal, a variable-impedance transmission coupler, and a variable-impedance reception coupler.
