DISPOSICION DE CIRCUITO PARA LA RECEPCION DE SENALES ELEC- TRICAS DE ALTA FRECUENCIA.

摘要

A circuit which steps up a substantially pure antenna resistance to a high value which is constant across a wide frequency band. The circuit features a parallel resonant circuit coupled to the antenna and fixed tuned to a frequency at one of the band limits. A series reactance couples the fixed tuned circuit to a circuit which is tunable across the band and is the input of an R.F. amplifier.
