TUA2009XS - VHF I / VHF II / UHF-Tuner

General Description

This integrated circuit permits the design of TV-tuners covering the entire frequency range from 48 … 900 MHz split into 3 frequency bands.

The application is suitable for all tuners in TV- and VCR-sets.

Key Features

  • q Few external components q Frequency and amplitude-stable unbalanced oscillator for the VHF I-frequency range q Frequency and amplitude-stable balanced oscillators for the VHF II- and UHF-frequency range q Optimum decoupling of input frequency from oscillator q Double balanced mixer with wide dynamic range and highimpedance inputs for the VHF I-frequency range q Double balanced mixer with wide dynamic range and lowimpedance inputs for the VHF II- and UHF-frequency range q Low-impedance SAW-filt.
