120 GHz Transceiver TRX_120_067
The IC module TRX_120_067 is a compact radar front end in the 120-GHz ISM band between 122.0 and 123.0 GHz...
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.
Application
The radar chips provide measurement signals for distance and speed measurement of objects as an analogue signal. In comnbination with 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 measured 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
The high-frequency radar signal is already converted to a lower frequency in the radar front end IC. The IC’s output is an analogue signal with a frequency of max. 2 GHz. This allows for routing and signal 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, voltage stabilization, frequency modulation and AD conversion.

Differences between TRX 120_001 and TRA_120_002
The radar antennas of the TRA 120_002 are monolithically integrated on the silicon chip and encapsulated in the housing. To achieve increased directivity, the antennas of the TRX_120_001 were designed as larger patch antennas and integrated in a separate carrier from the circuit within the QFN package. This results in different sizes and performance characteristics of the two radar modules with respect to radiation, beam characteristics and range. These can be further optimized by a combined set-up of the radar ICs with silicon and plastic lenses or reflectors.
Bar Die
These chips are also available as bare die when bought in large quantities.
