Combined VHF Television Tuner and IF Strip
Harry S. Suzuki · IEEE Transactions on Broadcast and Television Receivers · 1966
This paper describes a video i-f amplifier and agc system combined with a commercially available VHF tuner to form a compact television "receiver" system. The printed circuit board of the video i-f and agc circuitry is completely shielded by a metal cover comparable in size to a miniature VHF tuner. The combined unit requires d.c. power and horizontal keying pulses from the main chassis and will provide video and 4.5 MHz sound outputs.
