摘要

Improvements in selectors v.h.f. With diodes of variable capacity, characterized in that the input filter consists essentially of two filters in parallel, one for band i and another for band iii, the latter carrying the serial switching diode, only the band i filter operating when said the diode does not conduct and originates when it leads that the signals to the band iii frequency pass through to the base of the transistor of the radio amplifier, while the band i goes to ground due to the very small reactance that form a set of coils.
