Title
(EN) INTERMEDIATE FREQUENCY ON CHIP (IFOC) SYSTEM
(FR) SYSTÈME DE FRÉQUENCE INTERMÉDIAIRE SUR PUCE (IFOC)
Abstract
(EN)
Techniques are disclosed implementing a radio partitioning architecture using multiple data streams over a single coaxial cable that does not require external RF filtering. This provides a flexible frequency scheme (e.g., using IF frequency adjustment) that enables the avoidance of Wi-Fi and LTE harmonics. The techniques include leveraging baseband filtering, which may be integrated with the radio head in a common radio frequency intergraded circuit (RFIC).
(FR)
L'invention concerne des techniques mettant en œuvre une architecture de partitionnement radio utilisant de multiples flux de données sur un seul câble coaxial qui ne nécessite pas de filtrage externe de RF. Cela fournit un procédé de fréquence flexible (par ex., à l'aide d'un ajustement en fréquences intermédiaires) qui permet d'éviter les harmoniques Wi-Fi et de LTE. Les techniques comprennent l'exploitation d'un filtrage de bande de base, qui peut être intégré à la tête radio dans un circuit intégré commun à radiofréquences (RFIC).
