Description

The FD25H is a passive bridge diode frequency doubler, designed

for use in the high volume commercial and test equipment applica-

tions. The design utilizes Schottky bridge quad diodes and broad-

band baluns to attain excellent performance. The use of high tem-

perature solder and welded assembly processes used internally

makes it ideal for use in semi-automated and automated assembly.

Environmental screening available to MIL-STD-883, MIL-STD-202,

or MIL-DTL-28837, consult factory.
