Oscillatore sinusoidale a frequenza variabile con la valvola JAN-CG-2C43
 

Qualcuno saprebbe suggerirmi un circuito elettronico per un oscillatore sinusoidale a frequenza variabile da…(meno possibile 100Hz? 1KHz? a circa 3GHz)con la valvola JAN-CG-2C43?
E' un vecchissimo triodo in vetro in versione coassiale (a faro) e zoccolo octal, con cui si facevano oscillatori in linea risonanti un quarto d'onda. FIno al gigahertz, a spanna fra le due guerre e dopo la seconda guerra mondiale.

2C43
Planar Triode
Base & Bulb ( GE1 & TT-5)
Application
The 2C43 is a triode of lighthouse construction designed for use as a Class C radio-frequency amplifier or pulsed oscillator at frequencies as high as 3370 MHz.The radio-frequency cathode connection is made through a disk-type capacitor which is incorporated in the tube. This results in a low-impedance radio-frequency path from the cathode to the external circuit.The envelope construction results in low losses, provides convenient electrode contact surfaces, and enables the tube to fit easily into coaxial circuits. Requires an octal socket.
