     This application note is essentially based on the SPICE code and the comments of the Extubes.lib tube model library created by Broydé and Clavelier, on their simulation of a MOSFET-pentode amplifier, and on their translation of the Electronique Radio Plans paper [B23]. This amplifier was actually build and used for special EMC measurements where a high amplitude wide-band RF current source was needed. The actual circuit is only slightly different and implements an Eimac 8072 beam tetrode (with a 1200 V power supply).
