Product Brief Features and key benefits RASIC™ - RON7701 High quality DRO on local oscillator Automotive Radar Dielectric Resonator Oscillator (LO) signal stability Balanced Gilbert-cell mixer for downconversion Built in test equipment (BITE) for THE RON7701 IS A SILICON GERMANIUM (SIGE) dielectric resonator oscillator (DRO) based 19GHz down-converter for the use within a PLL circuitry for automotive radar applications. The DRO uses an external ceramic resonator, is optimized for low phase noise as well as low frequency pushing and operates at typically 18GHz. The balanced mixer converts the by-4-divided signal of a 77GHz fundamental oscillator to around 1 GHz. With this product Infineon Sense&Control (SC) introduces the latest RF technology (B7HF200) with automotive qualification AEC-Q100 to the market. The 200GHz fT SiGe technology is part of Infineon’s in-house, high volume 8” production and offers outstanding performance levels. The product is offered as bare-die delivered on blue-tape.
