TEA6101 Datasheet Antenna Diversity Circuit

Manufacturer: NXP Semiconductors

Overview: INTEGRATED CIRCUITS DATA SHEET TEA6101/T Antenna diversity circuit Objective specification File under Integrated circuits, IC01 May 1992 Philips Semiconductors Objective specification Antenna diversity.

General Description

TEA6101/T Intended for multi-antenna FM car radio reception (antenna diversity system), the TEA6101/T selects the most favourable signal from one of up to four antennae.

Founded upon audible signal disturbance the criteria are derived from two signals: high frequency ponents (e.g.

spikes due to noise and multipath reception) and variations in signal level as a result of multipath reception or fluctuations in field strength.

Key Features

  • Ability to switch between up to four antennae.
  • Switching signal derived from two signals: the audio and the level signals.
  • Floating switching threshold adjusts switching rate to prevailing circumstances:.
  • increasing threshold due to excessive noise.
  • increasing threshold due to numerous level variations.
  • Memory for the most favourable antenna signal to overcome unnecessary switching.
  • Signal-dependent `soft` muting circuit.
  • M.
