OSTI ID:4237532
The prediction and measurement of the small signal frequency dependent parameters of a feedback pair employing 2N247 drift transistors are reported. The matrix method of circuit analysis is used and the compatations carried out by digital computer. The precise measurement of the amplifier transfer function and input impedance over a wide frequency range is described. The method determined the two-port admittance parameters of the amplifier using a three terminal radio frequency bridge. Calculated and measured values of gain and input impedance are presented. Agreement in gain was +1 db out to 10 times the araplifier 3 db cut- off frequency. The values of input admittance are in reasonable agreement over the same frequency range. (auth)
