Sometimes he's all wound up about a microwave topic; other times it's random stuff like New Orleans Jazz, SUVs, or Gilligan's Island. The requirements were: Input frequency is a 5MHz sinewave into 50Ohms (I assumed a few dBm) Output frequency is 60kHz (a factor of 250/3, this is 83. The amplified signal is fed into the divide by N circuit. Manufacturer of RF power and frequency dividers. 12 - 18 GHz. Frequency Dividers, Multipliers, & Detectors ADI's frequency dividers, frequency multipliers, and frequency detectors offer high performance, ultralow phase noise and fast frequency lock time options for frequency muliplication, division and detection to meet the demands of modern technology. for this purpose i need a freq divider ckt. It can operate to 7. IEEE Radio Frequency Integrated Circuits Symposium, pp 87 – 90, June 1999. Numerous circuit topologies have been proposed for divide-by-¿ injection-locked frequency dividers (ILFDs), most of which have been optimized for division by even numbers, especially divide-by-2. In this dissertation, we focus on the analysis of the phase. The highest operation frequency achieved is 8. 92mm, BNC, N or SMA connector types. One form of divider, the regenerative frequency divider, is very useful in low-phase-noise frequency synthesis [1-4]. The low phase noise of the divider makes it ideal for generating low jitter, synchronous clocks in telecom applications. Available in subsets operating between the 400 kHz to 26 GHz frequency range, our dividers and combiners are characterized as both 50 and 75 ohm devices.
