Title: Low noise converter
Inventor: MOTOYAMA KOJI
IPC: H04B1/26
Filed: 2000-10-10
Abstract: PROBLEM TO BE SOLVED: To provide a low noise converter comprising a drive circuit which can supply a stabilized voltage to a transistor performing frequency conversion without being affected by ambient temperature variation. SOLUTION: In the mixing circuit (MIX) of a converter, a bipolar transistor Tr2 is connected as a temperature characteristic compensating circuit 11 between the base of a bipolar transistor Tr1 in a drive circuit 10 and a positive power supply node 23. Since collector current of the transistor Tr1 increases due to temperature characteristics of the transistor Tr1 when the ambient temperature of the drive circuit 10 increases, drain voltage of a high electron mobility transistor 50 is shifted in decreasing direction. But since collector current of the transistor Tr2 in the temperature characteristic compensating circuit 11 also increases to increase the voltage at point B1, increase of collector current of the transistor Tr1 is suppressed thus stabilizing drain voltage of the transistor 50.
