Description
The Isolink APD series of silicon PIN diodes are designed for use
as switch and attenuator devices in high-performance RF and
microwave circuits. The PIN diode designs are useful over a wide
range of frequencies from below 100 MHz to beyond 20 GHz.
These devices use a well-established silicon technology resulting
in PIN diodes with tightly controlled I-region characteristics.
The low capacitance and low resistance of the APD0505 through
APD1520 diodes are ideal for switch applications that require
insertion loss and fast switching speed. For switch or attenuator
applications requiring high power and low distortion, the thick Iregion
and high reverse breakdown voltage of the APD2220 is
ideal.
The absolute maximum ratings of the APD diode series are
provided in Table 1. Electrical specifications are provided in
Table 2. Typical performance characteristics are provided in
Figures 1 through 6.
