Abstract : Two types of broad-band solid-state limiters are investigated for protecting receivers operating in the 400 to 800 Mc range: ferrite limiters and varactor-diode limiters. Gallium-substituted yttrium-iron garnet is being considered for use in the ferrite limiters. Two crossed striptransmission-line half-wave resonators orientedAT RIGHT ANGLES TO ONE ANOTHER ARE BEING CONSIDERED AS THE BASIC LIMITING STRUCTURE. Two types of varactor diodes were considered for use in nonparametric limiter--PN and PIN. The amount of receiver protection and the burnout properties of these diodes were investigated. Measurements made of the dynamic range, spike leakage, and insertion loss over an octave range in the UHF region yielded good verification of the theory. The design equations for a 4 to 8 Gc strip transmission-line Y-junction circulator were obtained but not verified experimentally. Investigation of the design of broadband lownoise C-band amplifiers was started. (Author)
