Intensifiers in networks and electronic systems have
many uses. These circuits have a functional role in
oscillators, adjusting amplifiers, frequency meters,
phase regulators and band-pass and band-stop filters.
Below 300 MHz, intensifier circuits are usually formed
from compact inductors and capacitors. But these
circuits with compact elements at microwave frequencies
have defects.
First,
the condition that element dimension must be smaller
than the frequency wave-length limits their capacity,
voltage and current. Second, it is difficult to obtain
the necessary inductance and capacitance for high
microwave frequencies, particularly for high Q circuits.
Additionally, circuits at high frequencies tend to
radiate, causing power loss. Electo-ceramic is used to
overcome these limitations in microwave intensifier
circuits.
