Antenna diversity circuit
Objective specification
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.
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.
APPLICATIONS
• Car radio receivers
• Mobile radio communications equipment
