Abstract

PURPOSE:To obtain a filter having a high selectivity characteristics over a wide frequency range with a simple constitution, by securing a connection of a tunnel diode to which the bias voltage is applied plus a frequency serial resonance circuit to the secondary side of a transformer. CONSTITUTION:The primary winding 2a of the transformer 2 is connected to the input terminal 1 and output terminal 10. The one end of the secondary winding 2b is connected to the base line 11 after connected in series to the loss resistance 6, tunnel diode 3 and accumultor 8, and the other end of the winding 2b is connected directly to the line 11. In addition, the tuning variable accumulator 5 is connected to the secondary winding 2c. Thus a serial resonance circuit is obtained. The bias voltage is applied to the diode 3 from the DC power source 9. When the value obtained by multiplying the negative resistance of the diode 3 by the coupling coefficient of the electromagnetic induction, connection becomes approximate to the value of the resistance 6, the serial resonance circuit has a large definition. As a result, a filter having a high selectivity characteristics over a wide frequency range can be obtained.
