Document History

Description

The BEA T4 is a 24GHz K-band Doppler transceiver with active antenna. Based on an advanced oscillator with low power consumption. This dual channel transceiver enables the detection of moving object with direction information. Thanks to its unique transmit and receive antenna, it offers a symmetrical radiation pattern. With its active switch it allows to electrically change the radiation pattern from wide to narrow field.
