Analysis of Nonlinear Characteristics and Transient Response of IMPATT Amplifiers

Nonlinear analysis of synchronized microwave Gunn oscillators with the use of Volterra series

“…(16), we find that the maximum output power can be achieved when g, = -;al and the maximum output power is given by 4 P = -. OP 6 a , (17) Equation (17) is in agreement with the result obtained in [9], except that the coefficients are different because of the difference in the definition of power.…”

“…The radiation field of a broadside array with isotropic antennas is known as [9] n Z 0 where k = 2 r / A = propagation constant, N = half number of element antennas, 4 = azimuthal angle, x,, = nth antenna position, In = nth antenna current weight, and C = a constant that normalizes the maximum radiation power to unity (0 dB).…”

“…Phase lock principles are utilized in signal processing at radio frequency as well as higher frequencies. At microwave and millimeter wave regions the principle of injection synchronization is commonly used because of the simplicity of circuit arrangement (Cullen & Forrest, 1974;Biswas et al 1981;Biswas et al 1983;Kuno, 1973;Daikoku, & Mizushima, 1971;Kurokawa, 1973;Gustafsson, Lundstrom & Hansson, 1973;Hines, 1970;Nakajima & Ikenouse, 1978;Takayama, 1972). In microwave and millimeter wave regions of the spectrum, mostly solid-state oscillating devices like Gunn diode, IMPATT, etc.…”
