Selecting VCOs for Clock Timing Circuits – A System Perspective

Clock Timing, Phase Noise and Bit Error Rate (BER)

Timing is critical in digital systems, especially in electronic systems that feature high-speed data converters and high-resolution sampling. A clock source is the “timekeeper” and the system performance depends upon the effectiveness of this component. For some system designers, implementing a clock source automatically means using a crystal oscillator, typically a single-frequency source. But other designers, especially those tasked with synchronizing systems at multiple clock frequencies, have learned to appreciate the flexibility of using voltage-controlled oscillators (VCOs) as clock sources.

Update from Mini-Circuits

Fast-Switching GaAs Switches Are a High-Performance, Low-Cost Alternative to SOI

A mistaken belief has arisen in recent years that SOI has somehow taken over as the prevailing technology for fast RF switch applications. However, Mini-Circuits has recently introduced the M3SWA2-63DRC+ and the M3SWA2-34DR+ultrafast, absorptive RF switches which has given cause for designers to reconsider their switch choices. Designers are discovering that it is no longer necessary to bear the expense of an SOI switch just to get the speed they need. 

In this application note, a comprehensive, side-by-side, parametric comparison of the Mini-Circuits’ wideband GaAs MMIC M3SWA2-34DR+ switch to two SOI competitive offerings is performed. This comparison leads to the conclusion that there is no reason to take the foot off the GaAs.

Cavity Filters 300 Mhz to 50 GHz

High Rejection & Selectivity

Cavity filters achieve much higher Q, steeper rejection skirts, and higher power handling than other filter technologies, such as ceramic resonator filters, and are utilized where low passband insertion loss and high rejection of neighboring channels/spurious emissions are critical. Applications include military and commercial fixed site and mobile networks, as well as satellite communications.

Measurement of Amplifier Additive Phase Modulation Noise (APM)

Part 1: Background & Theory

Optimum APM Test Configuration

In the efforts to properly characterize the Additive Phase Modulation Noise (APM) and Additive Amplitude Modulation Noise (AAM) performance of MMIC amplifiers in the lab, it is important to consider the performance capabilities and limitations of phase noise analyzer and test setup (see Figure 4).  Both APM and AAM performance can be dependent upon the analyzer’s internal signal source carrier frequency, power level, and, importantly, the phase length from signal source output to RF input, so great care must be taken to optimize these parameters.

Frequency Modulation Fundamentals.

Originally a Solution for Eliminating Static.

Beginning in 1923, in Columbia University’s Marcellus Hartley Research Laboratory, in the basement of Philosophy Hall, a driven genius in electronic circuitry named Edwin Howard Armstrong set out to reduce static through the use of FM. After approximately 8 years of toil, Armstrong had a brainstorm and decided to challenge the assumption that the FM transmission bandwidth had to be narrow to keep noise low.

Frequency Modulation Fundamentals

Originally a Solution for Eliminating Static.

In the 1920s, many brilliant scientists applied themselves to the study of frequency modulation (FM). One of these scientists was a communications systems theorist who worked for AT&T named John Renshaw Carson. Carson performed a comprehensive analysis of FM in his 1922 paper which yielded the Carson bandwidth rule.1 Carson was so convinced that FM was not a suitable solution to the static found in AM transmission systems that he once remarked, “Static, like the poor, will always be with us.”2

Beginning in 1923, in Columbia University’s Marcellus Hartley Research Laboratory, in the basement of Philosophy Hall, a driven genius in electronic circuitry named Edwin Howard Armstrong set out to reduce static through the use of FM. After approximately 8 years of toil, Armstrong had a brainstorm and decided to challenge the assumption that the FM transmission bandwidth had to be narrow to keep noise low.

The Basics of Orthogonal Frequency-Division Multiplexing (OFDM)

While traditional Frequency Division Multiplexing has been around for over 100 years, Orthogonal Frequency Division Multiplexing (OFDM) was first introduced by Robert W. Chang of Bell Laboratories in 1966.1,2,3,4 In OFDM, the stream of information is split between many closely-spaced, narrowband subcarriers instead of being relegated to a single wideband channel frequency.5 Single-channel modulation schemes tend to be sequential whereas, in OFDM, many bits can be sent in parallel, simultaneously, in the many subcarriers.5 So many bits can be packed onto the subcarriers simultaneously that the data rate of each subcarrier’s modulation can be much lower than that of a single-carrier architecture.
