Abstract

Viene proposto un circuito per generare segnali a radiofrequenza per antenne a scansione elettronica ed in particolare per sistemi TACAN, ed uno sfasatore particolarmente adatto per tale circuito. Invece di utilizzare circuiti basati su grossi matrici di Butler, come tradizionalmente viene fatto, utilizzando una matrice di Butler piccola per combinare un numero limitato di uscite di un divisore di potenza e combinando ulteriormente le restanti uscite del divisore di potenza e le poche uscite della matrice di Butler attraverso l'uso di combinatori elettromagnetici si ottiene una pluralità di segnali a radiofrequenza adatti ad antenne a scansione elettronica con un notevole grado di precisione ed una circuiteria relativamente semplice.
