Filed: 1998-06-26
Abstract: PROBLEM TO BE SOLVED: To obtain a transmitting circuit which has excellent temperature characteristics by providing a control circuit that outputs a control voltage which is invariably constant irrelevantly to variation in ambient temperature to a power amplifier. SOLUTION: This transmitting circuit varies the base voltage Vb of a transistor(TR) 62 by adjusting a variable resistor 66 of the control circuit 61.

Further, this control circuit 61 generates an emitter voltage Ve (gate voltage Vg) which is always constant irrelevantly to whether the ambient temperature rises or falls after the adjustment.  Namely, the gate voltage Vg of the power amplifier 53 becomes constant irrelevantly to the ambient temperature, so this transmitting circuit improves temperature characteristics, the current value of the power amplifier 53 can be controlled to the prescribed value irrelevantly to the ambient temperature, and transmission output can be maintained at the prescribed value.

Abstract: PURPOSE:To realize a balance characteristic being equal to the time of using a mechanically variable resistance, and also to make the titled circuit small in size, by setting a base voltage of a transistor and a voltage drop of a resistance to a prescribed value, when a balance control voltage is equal to a reference voltage. CONSTITUTION:When a balance control voltage VBAL of a terminal 11 is equal to a balance control reference voltage VB of a terminal 12, a base voltage of a transistor (TR) 8 becomes VB/2-VBE, the TR 8 becomes off and a base voltage of a TR 14 becomes about '0'V.

In this way, even if a balance is in channel 1 side, its output Vo1 becomes the same as that of the time when the balance is in the center. Also, in case of VBAL=VB, even if the balance is in a channel 2 side, its output Vo2 becomes the same as that of the time when the balance is in the center, in the same way.
