Objective specification
Antenna diversity circuit
TEA6101/T
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
Mode selection to the first antenna receiving an AM
signal whilst the diversity system is reset.
APPLICATIONS
Car radio receivers
Mobile radio communications equipment
GENERAL DESCRIPTION
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 components (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.
