    • An object of the invention is to provide a transmitter high in efficiency, good in linearity and capable of covering an output level in a wide range. Either linear operating mode or saturation operating mode is set as the operating mode of a high-frequency power amplifier (15) on the basis of an operating mode set signal (107). The gain of a variable gain amplifier (14) provided in front of the high-frequency power amplifier (15) and values of output voltage (109) and bias current supplied from a supply voltage/bias current control circuit (17) to the high-frequency power amplifier (15) are switched. The gain of the variable gain amplifier (14) in the saturation operating mode is formed so as to be higher by a predetermined value than that in the linear operating mode. Accordingly, the high-frequency power amplifier 15 operates in the designated operating mode, so that the output transmission power range can be widened.
    • 本发明的目的是提供一种效率高,线性好并且能够在宽范围内覆盖输出电平的发射器。 基于操作模式设定信号(107),将线性运行模式或饱和运行模式设置为高频功率放大器(15)的运行模式。 设置在高频功率放大器(15)前面的可变增益放大器(14)的增益和从电源电压/偏置电流控制电路(17)提供给高电平的输出电压(109)和偏置电流的值 频率功率放大器(15)被切换。 饱和运行模式中的可变增益放大器(14)的增益形成为比线性运行模式中的预定值高。 因此,高频功率放大器15在指定的工作模式下工作,从而可以扩大输出传输功率范围。

    • To provide an image shake correcting optical apparatus using a small, lightweight engaging mechanism for the correction lens holder engaging mechanism. A ring-shaped engaging member 16 formed of shape memory alloy and having three engaging arms on its inside is located outside a lens holder 11 for a correction lens L3, and the engaging contacts 16b at the tips of the engaging arms 16a are pushed toward the center of the ring-shaped engaging member by means of coil springs 17. The engaging member 16 formed of shape memory alloy has a prescribed memorized shape so that the arms 16a will assume a retracted position, and where no heat is applied, the engaging contacts 16b of the engaging arms press onto the lens holder 11 for the correction lens L3 from the outside due to the spring force of the coil springs 17, and engages with and maintains in place the lens holder 11. Where heat is applied, the engaging arms 16a retract, whereupon the engagement of the lens holder 11 is terminated.
