Abstract
PURPOSE: To suppress the increase in the chip temperature by reducing the bias current, through the cascade connection of the mixing circuit and the local oscillation circuit between the power supply terminal and ground and through the bias current flowing to them commonly.
CONSTITUTION: The emitter of the transistors Tr 13, 16 is commonly connected and is connected to the constant current, and the collector is connected to the common emitter of Tr11, 12 and that of Tr 14, 15. The input signal is fed to the base of Tr11, 12 and Tr14, 15 by feeding back from the collector of Tr13 to the base of Tr16 and from the collector of Tr16 to Tr13, to pick up output from the collector. Thus, the bias current commonly flows to reduce the bias current resulting in suppressing the temperature rise of the chip temperature.
