FD25 / FD25C / FD25E / SFD25 Frequency Doubler Rev. V4 Features Product Image Input 5 to 2400 MHz Output 10 to 4800 MHz Input Drive level +10 dBm (nominal) Hermetically-Sealed Package 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.
