摘要： PURPOSE: A terminal for a mobile communication system is provided so that transmission spurious property can be improved by removing 8.192MHz clock noise of a baseband, by adding IQ low band filters to a preceding terminal of an QPSK modulator. CONSTITUTION: A low band filter(101) removes 8.192MHz frequency from a baseband signal processor by filtering an IF baseband signal. A QPSK modulator(102) modulates the baseband signal from the low band filter(101). An LC band filter(103) passes a necessary frequency band by filtering the intermediate frequency from the QPSK modulator(102). An auto gain controller(104) controls a gain of the transmission signal. A frequency up converter(105) converts the transmission signal from the auto gain controller(104) to a radio frequency. A radio frequency band filter(106) filters the radio frequency from the frequency up converter(105) to a predetermined band. A pre-amplifier(107) amplifies the output signal from the radio frequency band filter(106). A drive amplifier(108) amplifies the output signal from the pre-amplifier(107) to a predetermined level. A final amplifier(109) amplifies the output signal from the drive amplifier(108) As the result, transmission spurious property is improved without requiring a saw filter. In addition, current consumption of the amplifiers can be remarkably reduced by removing the loss of the transmission signal.

摘要： The invention relates to an analog bandpass filter comprising a plurality of LC ladder circuits (1), the response from which is determined by a passband (fpi, f ps) and a rejection band (with limits fri and frs). The inventive filter is characterised in that a series of tank circuits (5) is disposed in parallel to the filter charge, the resonance frequencies of said tank circuits coinciding with the lower (fpi) and upper (fps) cut-off frequency of the pass-band of the filter. Furthermore, the filter comprises a control resistor (Rc) which regulates the effect of the tank circuits on the filter. Said structure can be used to compensate the effect of the real limitations of the LC components (1) in order to adjust the response from the analog bandpass filter created with said components to the response from the ideal bandpass filter.
