Description

The FD25 is a passive bridge diode frequency doubler, designed

for use in military, commercial and test equipment applications.

The design utilizes Schottky bridge quad diodes and broadband

soft dielectric and/or ferrite baluns to attain excellent performance.

The use of high temperature solder assembly processes used

internally makes it ideal for use in manual and semi-automated

assembly.

Environmental screening available to MIL-STD-883,

MIL-STD-202, or MIL-DTL-28837, consult factory.
