When High Performance Matters


The Finest Architecture For Your Special Needs

NIRSEN analog IPs use a 60 GHz non-licensed frequency band (57-64GHz) and a 77-81GHz automotive band, allowing worldwide operation in non-automotive and automotive markets, respectively. Our IC designs offer a basis for a full and natural vertical integration of the custom radar sensing modules as the main advantage. Thus, on one side NIRSEN radar IPs lead to cost-effective radar module solutions for various applications. On the other, analog radar IP parts may be used to replace the old radar sensor front ends by remaining existing signal processing part. Own custom radar chip developed by NIRSEN using NIRSEN IPs brings to our customers a 100% supply chain control, and clear differentiation from other competitors using off-the-shelf radar sensing silicon. We can develop custom solutions either for large or niche markets segments, with high performance and high reliability, as well as full customization. Ability to get associated application-driven firmware solutions is rounding up NIRSEN offering.

RF IP: 60 GHz 1Tx-1Rx mmWave Radar

This FMCW transceiver chip is at the heart of the 55–64-GHz fully integrated radar module. The silicon achieves sub-2-cm spatial resolutions and enables cutting-edge modulation rates higher than 200 MHz/μs. The radar reaches the leading edge 10-GHz chirp bandwidths. It is intended for short-range applications, even below the 5-cm range. This 60 GHz IC can be used as a basis for custom nTx-mRx radar transceiver IC.
