Ipx-551 | 2027 |

IPX‑551 outperforms existing electronic front‑ends in NF and SFDR while consuming ~50 % less power. Compared with earlier photonic prototypes, the IPX‑551 achieves a (≈ 3 mm²) and eliminates the need for an external high‑speed ADC , thanks to the monolithic SAR ADC.

Despite this promise, prior photonic‑receiver demonstrations have been limited by , high optical‑pump power , or inadequate integration of digital conversion [5,6]. The IPX‑551 project was conceived to address these gaps by integrating silicon‑nitride waveguide photonics , a low‑Vπ electro‑optic phase modulator , and a balanced germanium photodiode pair , all fabricated on a 200‑mm CMOS‑compatible platform. The resulting architecture delivers a compact, low‑power, high‑dynamic‑range front‑end suitable for mass production. IPX-551
