The focus of radar MMIC TRA_120_002 is on maximum integration. Here both antennas, one for transmitter and one for receiver branch, are monolithically integrated in the chip to offer lowest size and loss. Please also see our hybrid integrated MMIC radar TRX_120_001.
The radar chips provide measurement signals for distance and speed measurement for objects as an analogue signal. Including a subsequent external signal evaluation at customer side possible applications are the investigation of a material surfaces, the measurement of layer thicknesses and other properties of the measurement objects. The main application area of the 120-GHz transceiver radar front end is for short-range radar systems with an operation range of up to 10 meters. By using dielectric lenses or mirrors, the range can be increased beyond 100 metres.
No handling of high frequencies on PCB
In the radar front end, the high-frequency radar signal is already converted to a smaller frequency in the IC. It is output as an analogue signal with a frequency of max. 2 GHz. This allows for routing andsignal processing of all signals on cost-efficient PCBs. It can therefore be implemented on standard FR4 boards and combined with other IC components for control loops, for voltage stabilization, frequency modulation and AD conversion.
