Abstract
Performance data of a two-sided shunt-type diode-stabilitron amplitude limiter, in which a stable limiting threshold is specified by the breakdown voltage of the stabilitrons connected in series opposition to the diodes, are measured at 30 MHz in a low-voltage range. It is established that the limiter factor may exceed 100 when the stabilitrons are automatically biased to the breakdown region owning to rectifying of a limited signal by the diodes; it may reach 1000 when they are biased from a power source of the amplifier. The operating conditions for attaining a high limiter factor are determined.
