Description
TO-8
Flatpack
The FD25H is a passive bridge diode frequency
doubler, designed for use in the high volume
commercial and test equipment applications. The
design utilizes Schottky bridge quad diodes and
broadband baluns to attain excellent performance.
The use of high temperature 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.
