The 435-36105 from Cobham is a Frequency Synthesizer that operates from 450 MHz to 18.25 GHz with 10 MHz steps. This device provides a switching speed of 250 µs from any start frequency to any stop frequency in the full range and has a parallel control interface to facilitate pipelined hopping. The spurious content is -55 dBc from 450 MHz to 12 GHz and -50 dBc from 12 to 18.25 GHz. Subharmonics are -20 dBc throughout the frequency range and second harmonics are -12 dBc. It operates from a +5 V DC supply, drawing 1.25 A of current. The synthesizer is available in a module that measures 2.6 x 2.6 x 0.6 inches with SMA connector. It is built to operate under the conditions of shock, vibration, and temperature typically found in severe military environments.
