PROBLEM TO BE SOLVED: To provide an electronic circuit unit which is suitable for miniaturization and the output of which can be adjusted easily. SOLUTION: In this electronic circuit unit, circuit elements containing capacitors Cl-C7, resistors R1-R3, inductance elements L1-L3, etc., are formed on an almuna substrate 1 in the form of thin films, and a bare semiconductor chip of a diode D1 and a transistor Tr1 is wire-bonded. In addition, the voltage dividing resistors R1 and R2 for base biasing of the transistor Tr1 are formed closely to each other on the substrate 1 in the form of thin films. |
