摘要： Radio communication systems, e.g. cellular telephones, have employed a space diversity antenna system which includes a plurality of antennas. In the space diversity antenna system for use in the cellular telephone, since two antennas are positioned adjoining each other, the space diversity effect cannot be adequately provided. To solve this problem, the polarization diversity antenna system according to this invention incorporates a first antenna, a second antenna, and a conductive board on which the second antenna is fixed at a given position, thus preventing the current flowing in the conductive board from causing the reception characteristic of the second antenna to deteriorate.

摘要： Provided is an oscillation frequency control circuit for correcting its frequency, keeping the oscillation frequency stable when self-oscillating, and oscillating with a control voltage generated by making a fixed voltage given from outside variable. In the oscillation frequency control circuit, a CPU selects/outputs the control voltage preferentially according to a command of a control voltage selection. If the command is not given and the level of an outside reference signal detected by a detecting circuit is within an adequate range, it turns a select switch on. If the command is not given and the level of the outside reference signal is out of the adequate range, it turns the select switch off and outputs information about pulse generation stored in a memory to a PWM circuit.

摘要： With an amplifier configured by including Doherty-type amplifier sections 21 to 25, the area of the circuits is reduced so that the size reduction is achieved. Moreover, the properties of the Doherty-type amplifier sections (Doherty properties) are stabilized against any environmental change of humidity and temperature. As an example, the permittivity of a substrate 3 configuring one or more of quarter wavelength lines 23 and/or 24 included in the Doherty-type amplifier sections 21 to 25 is increased compared with the permittivity of a substrate 2 in a close range. As another example, a line portion forming an output circuit of a carrier amplifier in the Doherty-type amplifier sections is configured by using a substrate material being physically stable against either or both of any change observed in the humidity and the temperature.
