Low-Cost Programmable Oscillator Operates at 2 GHz - 05/11/00
EDN-Design Ideas.....All wireless communication systems need a local
oscillator. Figure 1 shows a low-cost PLL circuit for the 2-GHz band for
such applications as industrial, scientific, and medical (ISM]and
satellite personal-communication systems (S-PCS]. The central..... EDN is

Low-cost RF synthesizer uses generic ICs - 24-Jun-10 Issue of
EDN You can design a hardware-based frequency synthesizer with one
inexepensive IC and a few passive components. Such synthesizer chips are
not always available, however, because they are typically single-sourced
and are not in stock with parts distributors. The need for a working
circuit in a short time and using common parts prompted the creation of
the circuit in this Design Idea. The synthesizer covers the US commercial
AM (amplitude-modulation) broadcast band. It tunes in 10-kHz steps from
500 to 1800 kHz, but you can scale the frequencies for other
applications..... [Design Idea by James B Wood, Inovonics Inc, Felton, CA]
