ADF5001:  Предварительный делитель частоты диапазона 4 ГГц - 18 ГГц с коэффициентом деления 4

Информация о продукте

Статус продукта:Производство

Предварительный делитель частоты ADF5001 - это малошумящий, малопотребляющий ВЧ делитель с фиксированным коэффициентом деления. Он может быть использован для деления частоты входного сигнала в диапазоне до 18 ГГц в целях получения сигнала меньшей частоты, который может быть подан на вход ИМС синтезаторов с ФАПЧ, например, ADF4156 или ADF4106. ADF5001 обеспечивает функцию деления частоты на 4. Компонент работает от напряжения питания 3.3 В и имеет дифференциальные выходы ВЧ с импедансом 100 Ом, что позволяет подключать его непосредственно к дифференциальным ВЧ входам ИМС синтезаторов с ФАПЧ, таких как ADF4156 и ADF4106.

    Fundamentals of Frequency Synthesis, Part 1: Phased Locked Loops
    The first of a two-part series on frequency synthesis, with an introduction to Phased Locked Loops. This webcast looks at the need for frequency generation, the techniques from the past present and future, and how to assess the performance of a frequency synthesis, and real world applications. Particular attention will be focused on Phase Locked Loops (PLL's) as frequency synthesizers.

    Fundamentals of Frequency Synthesis, Part 2: Direct Digital Synthesis (DDS)
    This month we conclude our two-part series on frequency synthesis, with an introduction to Direct Digital Synthesis. We will give a basic review of how a direct digital synthesis system works, touching on the inner workings of the DDS engine at a relatively high level. We will also discuss the tradeoffs between PLL and DDS technology as a base choice for frequency synthesis needs.
