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.
