Description
M/A-COM produces a series of silicon PIN limiter
diodes with small and medium I-region lengths
which are specifically designed for high signal
applications. The devices are designed to provide
low insertion loss, at zero bias, as well as low flat
leakage power with fast signal response/recovery
times. Parts are available as discrete die or
assembled into a variety of surface mount or
cylindrical coax ceramic packages. See Available
Case Style table on page 6 for the specific
ceramic package styles and their availability for
individual part numbers.
Applications
The MA4L Series of PIN limiter diodes are
designed for use in passive limiter control circuits
to protect sensitive receiver components such as
low noise amplifiers (LNA), detectors, and mixers
covering the 10 MHz to 18 GHz frequency range.
