摘要：

Triode RF amplifier structures using field emission cathodes have been investigated from both the theoretical and experimental viewpoint. This paper describes the physically large experimental structure which has been used and the theoretical calculations on that structure. The agreement between theory and experiment for both dc and ac measurements is shown to be very good. The theoretical circuit modeling has produced information which will be useful in future work for higher frequency operation. RF voltage gain of about 11 dB has been measured at low frequencies, dropping to 0 dB at 200 kHz, with a cathode which had only 38-mu-S transconductance. Model calculations on the large structure used show operation to about 2 MHz with more typical transconductance of 380-mu-S for a 1000-cone field emission cathode.
