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.
