120-GHz IQ Transceiver TRX_120_001 Data Sheet Revision 1.4 2018-11-13 Application Circuit Schematic Application Circuit Power Cycling It is possible to reduce power consumption by power cycling the radar front end. Rapid power cycling with voltage rise times between 10 and 100 µs is possible. 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. Evaluation Boards For a quick and easy start into radar development Silicon Radar offers SiRad Easy®....

120-GHz IQ Transceiver TRX_120_001 Data Sheet Revision 1.4 2018-11-13 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. Otherwise, the supply current may be conducted through the upper ESD protection diode connected at the pin. The VCO tuning inputs Vt0 – Vt3 are of analog nature, but can be switched digitally as well. The tuning inputs differ in their tuning ranges (tuning bandwidth) and slopes, whereby Vt3 has the widest tuning range, and...
