The 1018 series of frequency synthesizers from Cobham is designed to meet the phase noise, spurious, and harmonic specifications required for airborne, shipboard, and laboratory environments. The product line features a parallel control interface to facilitate pipelined hopping, which enables switching speeds of up to and over 250 µs (typical) switching speed from any start frequency to any stop frequency in the full range. Smaller frequency steps typically achieve faster switching speed.
The family of synthesizers – which measures 2.6 by 2.6 by 0.6 inches and weighs just 0.25 lbs. – covers frequencies from 18 GHz in 10 MHz steps. The power requirement for the synthesizers is typically +5 VDC ±10 percent, at 1.25 amps. The compact synthesizers have an SMA port for connection to an external 10 MHz reference oscillator while maintaining the frequency stability of the external reference. The output power is calibrated to remain within a ±2-dB window when the frequency synthesizer is operated within ±5 °C of the calibration temperature. The units are built to withstand operating temperatures of -40 °C to +70 °C and storage temperatures of -55 °C to +85 °C on aircraft, aboard ship, and in the lab.
