Re: XRef - 10MHz-Locked Reference Oscillator Post by VK4FLR » Sun Feb 03, 2013 8:25 pm Yep - interested in one for my FT 847-have fitted a Kuhne precision xtal heater reg to the ref osc but it still drifts around a bit. Richard Patterson, NASA Glenn Research Center. This device integrates functions typically achieved with discrete components. PLO's are realized in one of the three architectures show below:. International prides itself on cutting edge design and engineering. I searched for an OCXO that provided very low phase noise, availability within 2-4 weeks, a cost under $200 and the option to buy in small quantities. 000MHz 10MHz OCXO Oven Controlled Crystal Oscillator 25. This one has done very nicely for about $100. •Hartley– The resonant circuit is a tapped inductor or two inductors and one capacitor. Determine the value of the capacitance such that the fifth harmonic is reduced by 20 dB in the gate voltage VG(t). 9 / Piece, Guangdong, China, WTL, WTL2. I needed it to also meet a low budget. Output signal is determined by supply current changes. Further investigation is warranted. (May 2009) James Keith Hodgson, B. Low-Noise Integrated PLL Synthesizes 10 MHz to 15 GHz This compact PLL works with a wide range of reference input signals to generate wideband output signals that are low in harmonics, spurious, and phase noise. ILSI RF, Crystal, and Clock Oscillator products, XO's, are supplied in a wide range of frequencies, many diff. This filter was designed by Wes, W7ZOI.
