A PTFE-free radar, with single receive-transmit MMIC based on TowerJazz’s SiGe CMOS technology, for the first time associated with a phased array antenna.

Denso DNSRR004 Blind spot radar

Denso Corp has developed a 24GHz submillimeter-wave rear and side radar sensor for detecting vehicles in adjacent lanes. Used in several Toyota sedan models, the radar is embedded into the rear bumper of the vehicle and can detect following vehicles likely to enter the driver’s rear and side blind spot.

The DNSR004 includes a Monolithic Microwave Integrated Circuit (MMIC) manufactured using SiGe CMOS Technology from TowerJazz. It combines transmitter (Tx) and receiver (Rx) features on a single chip in a Quad Flat No-Lead (QFN) Package. To enable accurate detection whether moving forward or reversing, a phase shifter switches the sensing direction and range of the submillimeter-wave radar sensor. Radio wave transceiver and phase shifter functions run through separate integrated circuits to reduce the size of the sensor. The radio frequency printed circuit board substrate is completely PTFE free, and uses glass-reinforced hydrocarbon ceramic laminate and integrates 20 Tx and 20 Rx patch antennas.

Based on a complete teardown analysis of the Denso radar, this report provides the bill-of-material (BOM) and the manufacturing cost of the radar sensor. The report also includes a physical analysis of the MMIC, complete cost analysis and selling price estimation.
