摘要： The present invention is directed to a TDMA communication system which is adapted to different communication environments or prepares different communication environments and allows each mobile station to be set for working in any one of the different communication environments. The communication system commonly uses a TDMA format that has a fixed frame-length and a constant number of bits for each of the slots composing the frame. The communication environments have prepared respective sets of communication conditions, each set including a transmission power, a modulating method, the number of multiplexed signals, error-correction, an antenna gain, a frequency hopping value and a diversity value. At each mobile station and each base station, one of plural sets of communication conditions for respective environments is selected to establish communication with each other under the selected environment.

摘要： A quadrature phase-shift keying modulator produces a QPSK signal which is amplified by a power amplifier. The amplitude gain of the power amplifier is controlled in response to an amplitude difference between the QPSK signal output by the modulator and the amplified QPSK signal output by the power amplifier. A phase detector, connected in series between the modulator and the power amplifier, eliminates amplitude variations from the QPSK signal prior to amplification. A voltage-controlled phase shifter, connected in series between the phase detector and the power amplifier, shifts the QPSK signal in phase by an amount responsive to amplitude information in the QPSK signal.

摘要： A radio receiver for data communication of the type handing digital signals has a radio frequency (RF) section for receiving an RF signal having a predetermined frequency band from an electromagnetic wave which comes in through an antenna. A first frequency converting section converts the RF signal received by the RF section to a first intermediate frequency (IF) signal. A first IF filter filters the first IF signal and is implemented by a surface acoustic wave filter. A second frequency converting section converts the output signal of the first IF filter to a second IF signal. A data amplifying section picks up the above-mentioned frequency band from the output of the second frequency converting section and amplifies the resultant, picked-up band. A detector detects the output of the data amplifying section. An equalizer corrects a deviation of group delay time with each of respective frequencies of the output of the detector.

摘要： A power amplifier system suitable for a mobile radio receiver/transmitter is described. A wave form signal to be transmitted is made smooth during its rise and fall times, thereby making it possible to prevent a transmission spectrum from expanding and interfering with the adjacent channels. The power amplifier system compares an envelope signal of an inputted RF signal and that of an RF signal to be outputted, whereby the power amplifier system as a whole provides linear amplification.

摘要： An output power control device is provided with an isolator, to which a transmission signal, that has been power amplified by a power amplifier, is input. The transmission signal is input via a transmission line connected to an output side of the power amplifier. The isolator only passes a progressive wave component of the transmission signal. The output power control device also includes a detection circuit for forming an actual output power detection signal by extracting part of an output power from a point of input of the isolator. Further, a reactance adjusting element connected to the point of input of the isolator cancels a parasitic reactance associated with the extracting section of the detection circuit.

摘要： According to a first aspect, a portable electronic device has at least two load circuits which are independently powered by different batteries. According to a second aspect, the load circuits are powered by the same battery, but their power lines are branched from a node located close to the battery, thereby reducing common impedance. According to a third aspect, two power lines are coupled through switches to two independent batteries, and are mutually coupled through a third switch. The switches are controlled according to the discharge states of the batteries. According to a fourth aspect, a battery charger charges two or more batteries by supplying current to them for short intervals in turn, so that all batteries reach full charge at substantially the same time.

摘要： A power control circuit having a saturation preventing control loop including a variable gain amplifier, an RF power amplifier, a directional coupler, a detecting circuit, a comparator, a switch, and an adder. When the signal level of an output signal of the comparator is low, the switch is turned on. When the signal level of the output signal of the comparator is high, the switch is turned off. A system power control loop includes a system power control terminal, the adder, and the variable gain amplifier. Since the saturation preventing control loop is provided with the switch, the saturation preventing control loop operates only when the signal level of the amplified signal is larger than a reference value. The system power control loop can properly operate according to a system power control signal supplied from the system power control terminal.
