TDA5745 - Low power mixers/oscillators for hyperband tuners

Datasheet Summary

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.

Features

Mixers/oscillators for hyperband tuners.
Balanced mixer with a common emitter input for VHF (single input).
Balanced mixer with a common base input for UHF (double input).
4-pin common emitter oscillator for VHF.
4-pin common emitter oscillator for UHF.
Electronic band switch.
IF amplifier with a low output impedance to drive the SAW filter directly (≈2 kΩ load).
Low power, low radiation and small size.
Pin compati.
