120-GHz Radar WB Transceiver TRAˍ120ˍ045 (T456) Data Sheet Version 0.3 13-Sep-2021 Application Circuit Schematic RXEN HPEN PWR DIVEN Application Circuit Power Cycling It is possible to reduce power consumption by power cycling the radar front end. Rapid power cycling can be implemented with voltage rise times between 10 and 100µs. At power-up, it must be ensured that no input signal is driven high before the supply voltage is stable. At power-down, all input signals must be pulled low before the supply voltage is switched off. For a quick and easy start into radar development Silicon Radar...

120-GHz Radar WB Transceiver TRAˍ120ˍ045 (T456) Data Sheet Version 0.3 13-Sep-2021 Input / Output Stages The following figures show the simplified circuits of the input and output stages. It is important that the voltage applied to the input pins never exceeds VCC by more than 0.3 V, which exception of VVT cf. Section 4.1. Otherwise, the supply current may be conducted through the upper ESD protection diode connected at the pin.
