cover Book Description
This unique, all-inclusive guide provides complete instructions for building a sophisticated yet low-cost microprocessor-controlled radio transceiver, as well as smaller projects such as simple frequency synthesizer and spectrum analyzer. Readers will get hands-on experience with interfacing digital and analog circuitry, fabricating circuit boards, anticipating the real-world behavior of RF circuits, and more includes circuit-board layouts, parts lists, and schematic diagrams.



cover Book Description
* Provides complete design procedures for multiple-pole Butterworth, Chebyshev, and Bessel filters * Covers capacitors, inductors, and other components with their behavior at RF frequencies discussed in detail
