Title
(EN) RADIO FREQUENCY REMOTE HEAD FRONT-END CIRCUITRY SYSTEMS AND METHODS
(FR) PROCÉDÉS ET SYSTÈMES DE CIRCUIT FRONTAL DE TÊTE DISTANTE RADIOFRÉQUENCE
Abstract
(EN)
Techniques for implementing and/or operating a radio frequency system 12, which includes a logic board that outputs an analog electrical signal indicative of data to be wirelessly transmitted from the radio frequency system 12 and a remote head 78. The remote head 78 includes an antenna 34 that generates an electromagnetic wave to facilitate wirelessly transmitting the data, an antenna integrated circuit 96 implemented using a first semiconductor manufacturing technique, in which the antenna integrated circuit 96 amplifies the analog electrical signal to generate a first amplified analog electrical signal, and a remote front-end integrated circuit 98 coupled between the antenna integrated circuit 96 and the antenna 34. The remote front-end integrated circuit 98 is implemented using a second semiconductor manufacturing technique different from the first semiconductor manufacturing technique and amplifies the first amplified analog electrical signal based on a target output power of the antenna 34 to generate a second amplified analog electrical signal indicative of the data.

La présente invention concerne des techniques de mise en œuvre et/ou d'actionnement d'un système radiofréquence (12), qui comprennent une carte logique qui délivre un signal électrique analogique indicatif de données à transmettre sans fil depuis le système radiofréquence (12) et une tête distante (78). La tête distante (78) comprend une antenne (34) qui génère une onde électromagnétique pour faciliter la transmission sans fil des données, un circuit intégré (96) d'antenne mis en œuvre à l'aide d'une première technique de fabrication de semi-conducteur, dans laquelle le circuit intégré (96) d'antenne amplifie le signal électrique analogique pour générer un premier signal électrique analogique amplifié, et un circuit intégré frontal distant (98) couplé entre le circuit intégré (96) d'antenne et l'antenne (34). Le circuit intégré frontal distant est mis en œuvre à l'aide d'une seconde technique de fabrication de semi-conducteurs différente de la première technique de fabrication de semi-conducteurs et amplifie le premier signal électrique analogique amplifié sur la base d'une puissance de sortie cible de l'antenne (34) pour générer un second signal électrique analogique amplifié faisant état des données.
