... In large signal power or gain control applications (P > -20 dBm), the HSMS-282x and HSMS-286x prod- in ucts should be used. The HSMS-285x zero bias diode is not designed for large signal designs. Schottky Barrier Diode Characteristics Stripped of its package, a Schottky barrier diode chip consists of a metal-semiconductor barrier formed by de- position of a metal layer on a semiconductor ...
