Abstract
This report describes a design concept and its implementation for an all-channel transistorized TV tuner with common RF amplifier, mixer and local oscillator for both VHF and UHF TV bands. The VHF and UHF tuned circuits of each stage are mounted on a common wafer of the channel selector. Interaction between the VHF and UHF tuned circuits is eliminated by the novel use of ferrite beads and shielding. The result obtained by this design concept is a low cost, compact and simple all-channel TV tuner with single knob tuning capability. This work was done at Hazeltine Corporation, Hazeltine Research Division (Plainview, N.Y.), under a contract with Hazeltine Research, Inc.
