Title: High frequency gain control circuit
Inventor: MORI GIICHI
IPC: H03G1/04
Filed: 1985-11-08
Abstract: PURPOSE:To attain the gain control accurately and stably by connecting a Zener diode to a source of a dual gate FET (field effect transistor), controlling the source potential constant by the Zener voltage and controlling the high frequency gain by a positive voltage fed to the 2nd gate of the FET. CONSTITUTION:The source potential depends on the voltage of the Zener diode 112 and the current flowing to the Zener diode 112 minimizes the change in the source potential as less as possible attended with the fluctuation of the drain current by selecting the current sufficiently more than the drain current. Thus, the gain control of the circuit is attained by a positive potential only to the gate G2. When the relation between the potential of the gate G2 and the control variable is linear, the gain control circuit possible for the program control is realized very easily. In this case, 3-bit input and 8-step control are attained from terminals 116-118. An input 3-bit signal is converted into an analog quantity by a D/A converter 115, the result is fed to the gate G2 of the FET 103 so as to change over the gain in 8 steps for a certain step each.
