Description
The CSFD25 is a passive bridge diode frequency doubler, de-
signed for use in the high volume wireless and test equipment
applications. The design utilizes Schottky bridge quad diodes and
broadband baluns to attain excellent performance. Due to 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.
