... Hyperband tuners for Europe using a 2-band mixer/oscillator in a switched concept. GENERAL DESCRIPTION The TDA5744 and TDA5745 are 2-band mixers/oscillators intended for VHF/UHF and hyperband tuners (see Fig.1). The Integrated Circuits (ICs) include two double balanced mixers and two oscillators, for the VHF and UHF band, and an IF amplifier ...
