    摘要: In the frequency synthesizer, the stable transmission frequency required by the digital operating mode is created from a frequency produced by a free running oscillator and which includes frequency errors. A local frequency (f.sub.1) and an intermediate frequency (f.sub.IF) including frequency errors are input to a mixer (105) located in the signal path of the transmitter. A transmission frequency transmission signal (f.sub.TX) is input to a phase-lock loop with a voltage-controlled oscillator (103) that produces the local frequency (f.sub.1). Thereby the frequency error caused by the intermediate frequency (f.sub.IF) can be corrected with the local frequency (f.sub.1) by adjusting the voltage-controlled oscillator (103) of the loop with a voltage (V.sub.D) that is proportional to the phase difference between the transmission frequency signal and a reference signal (V.sub.REF) input to a phase comparator. This is implemented by connecting the mixer (105) to the loop during the transmission time period with a controllable switch (104), for example. The local frequency (f.sub.1) of the receiver is produced with the frequency synthesizer described in the present invention by disconnecting the mixer (105) from the loop. The invention can be applied in producing frequencies for radio telephones that include dual-mode operating modes and exclusively digital operating modes.

    摘要: The invention is based on utilizing the receiver of a radio device to detect measured quantities related to a transmission signal. In the power regulating method according to the present invention, which is based on a power regulating loop, transmission power is detected in the receiver of the radio device. Part of the transmission signal (f.sub.TX) is input to the carrier frequency part of the signal path of the receiver by and detected. A signal that is proportional to the power level is produced by a RSSI detector of the receiver, for example. The same circuit can also be utilized in the linearization of a transmission signal based on a closed loop by means of predistortion. Both the power regulation method and the linearization method can be applied in radio telephone systems based on both time-division and continuous transmission and reception.

    摘要: The output frequency of a frequency synthesizer (21) according to the present invention is a multiple of a transmission frequency and said output frequency is divided before modulation to produce the transmission frequency (fTX). In an advantageous embodiment, the frequency synthesizer produces a frequency that is twice the transmission frequency, which is divided by a divide-by-2 divider to produce 90°-phase-shifted transmission frequency components required by a transmission frequency quadrature modulator. A simple, disturbance-tolerant transmitter construction is achieved by means of the present invention.
