Abstract
(EN)
Radar circuitry can include an isolator and a mixer. The isolator can isolate a transmission signal path and a reception signal path from each other, and generate a mixing (e.g. oscillation) signal based on a transmission signal. The isolator can be coupled to the mixer such that the drive signal drives the mixer (e.g. serves as the local oscillation signal of the mixer). The mixer mixes a received signal and the drive signal to generate a converted signal (e.g. a down-converted signal). The isolator can be a hybrid transformer or electrically balanced duplexer.

Des circuits de radar peuvent comprendre un isolateur et un mélangeur. L'isolateur peut isoler un trajet de signal de transmission et un trajet de signal de réception l'un de l'autre, et générer un signal de mélange (par exemple, oscillation) sur la base d'un signal de transmission. L'isolateur peut être couplé au mélangeur de telle sorte que le signal d'attaque entraîne le mélangeur (par exemple, sert de signal d'oscillation local du mélangeur). Le mélangeur mélange un signal reçu et le signal d'attaque pour générer un signal converti (par exemple un signal abaissé en fréquence). L'isolateur peut être un transformateur hybride ou un duplexeur équilibré électriquement.
