rxn 7740–Single chip Transceiver for 76–77gHz
The rxn 7740 is a Silicon germanium (Sige) transceiver for automotive long and mid-range radar
(lrr/mrr) applications in the frequency range of 76–77gHz. it also features on chip pre-scalers
as well as sensors for output power and temperature. With this product, infineon is launching the
latest rf technology (B7Hf200) with automotive qualification Aec-q100 on the market.

ron 7701–dielectric resonance oscillator (dro)
The ron 7701 is a Silicon germanium (Sige) dielectric resonator oscillator (dro)-based 19gHz down-
converter for 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 typically
operates at 18gHz. The balanced mixer converts the by-4-divided signal of a 77gHz fundamental oscillator
to around 1gHz.
