The Agilent 11721A frequency doubler is an accessory that’s ideal for extending the usable frequency range of frequency synthesizers, signal generators, or other signal sources. Operating on 50 MHz to 1300 MHz input frequencies, it gives a doubled output in the 100 MHz to 2600 MHz range. The Agilent 11721A works best with any RF source that comes with an output in the 50 to 1300 MHz range. The 50-ohm passive circuit of the Agilent 11721A provides low spurious, low conversion loss, and exceptional flatness over its whole frequency range when operated above +10 dBm.
