Title:
TUNER
Document Type and Number:
Japanese Patent JPS63141416
Kind Code:
A
Abstract:
The RF stage (3) and local oscillator stage (7) of a tuner both include respective cascode connected dual gate field effect transistors (101;401, Fig 2) as the amplifying device and similarly configured tuned circuits (300; 500, Fig 2) coupled to the first gate electrodes (G1) of the field effect transistors. The tracking characteristics of the tuner are enhanced due to the similar amplifier and tuned circuit configurations.
