ABSTRACT:
A temperature compensated detector includes a series circuit formed by successively connecting a first resistor, a first diode, a second diode having a characteristic substantially equal to that of the first diode, and a second resistor, a third resistor, and a fourth resistor. A terminal supplied with a predetermined bias voltage is grounded through the series circuit. A high-frequency signal to be detected is supplied to a junction point between the first resistor and the first diode or a junction point between the second diode and the second resistor. A detected signal is derived from a junction point between the third resistor and the fourth resistor which are respectively connected to both ends of the second diode or the first diode to divide a voltage.
