Mini-Circuits | MCDI - Renewing Our Founding Values as a 50-Year-Old Startup

The Mini-Circuits story is well known to many in the RF and Microwave industry. Some know us for our advertising, some know us as one of the first companies to transform the pricing structure of RF components, and some know us through the personal relationships they had with Harvey Kaylie, our founder and chief executive for the first 50 years of our history.

FILTERING WITHOUT REFLECTIONS: Flattening Multiplier Chain Conversion Efficiency & More

Mini-Circuits | MCDI - FILTERING WITHOUT REFLECTIONS

A new class of filter, which exhibits broadband matched impedance at its ports, has recently been invented and made available. This new device, the reflectionless filter, has demonstrated a variety of benefits when used to replace conventional filters in a signal chain. This white paper briefly introduces the reflectionless filter and compares conventional filter and reflectionless filter behavior. Use cases are presented examining how reflectionless filters can improve system performance when used with mixers, ADCs, and receiver signal chains. Lastly, an experiment is described and test results presented to compare the conversion loss ripple in multiplier chains when reflectionless and reflective filters are used to filter spurious signals.

שי בקושי עזבו את לוח התכנון וכותרות העיתונים גדושות בהשערות לגבי היכולות הגלומות בתקנים אלו, ובתוך כל הרעש הזה אנחנו לא פעם שוכחים שהטכנולוגיות האלו יהיו תלויות במידה רבה בדור החדש של מהנדסי ת”ר (RF). שעליהם תוטל המשימה של פיתוח המעגלים והמערכות האלו עד למימוש החלום. קשה לקלוט את כמות הרבה של המוצרים החדשים שבהם תהיה משולבת תקשורת ת”ר במהירות רבה וברוחב פס רחב כאשר יתפרשו הרשתות האלחוטיות של הדור הבא, וכדי לתמוך בה התעשייה תהיה זקוקה למאגר עצום של כשרונות טכניים.

Specifying VCOs for Clock Timing Circuits | Application Note

Specifying VCOs for Clock Timing Circuits | Application Note

Timing is everything for many systems, especially for modern electronic systems with high-speed data converters and high-resolution sampling. A clock source is “the keeper of time” in these systems and system timing performance is very much dependent upon the performance of its clock source. For some system designers, a clock source automatically means a crystal oscillator, typically a single-frequency source. But some system designers, especially those faced with synchronizing systems at multiple clock frequencies, have learned to appreciate the flexibility of using voltage-controlled oscillators (VCOs) as clock sources.

Reflectionless Filters Improve Linearity and Dynamic Range in Microwave Systems

Reflectionless Filters Improve Linearity and Dynamic Range in Microwave Systems

Filters are fundamental building blocks of nearly every modern RF/microwave system used to eliminate unwanted signals in receiver and transmitter architectures. Until recently, study and research in practical filter design has been largely devoted to topologies in which rejection of stop band frequencies is accomplished by reflecting undesired signals back to the source. Meanwhile, there are many applications in which these reflections produce intermodulation products, gain ripples, and other problems in system performance. For example, non-linear devices such as mixers, multipliers and high-gain amplifiers which respond to out-of-band frequencies are highly sensitive to the reflections caused by conventional filter designs. This becomes especially challenging as filters are often needed near or adjacent to active devices in the signal path to better define bandwidth or suppress unwanted harmonics.

Bridging the Gap between the University and the RF Industry

Bridging the Gap between the University and the RF Industry

With 5G standards barely off the drawing board and headlines filled with speculation about all the related capabilities, what sometimes gets lost in the buzz is that these technologies will depend heavily on a new generation of RF engineers to develop the circuits and systems to realize the dream. It is difficult to conceive of the number of new products that will incorporate high-speed, wideband RF communication once next generation wireless networks are rolled out, and the industry needs a deep pool of technical talent to support the demand.

Mobile and wireless communication has seen phenomenal growth over the past two decades. Faster communication with higher data rates has been the driving factor. To achieve this, the RF front end components have been continuously improved to meet the linearity and power requirements and a range of wireless standards have emerged, based on variations in frequency, modulation and power level requirements. The 0.7 GHz to 6 GHz band has been the mostly widely used frequency range for mobile and wireless communications using different standards such as GSM, CDMA, WCDMA, LTE, WLAN and WiMAX. The evolving 5G standard is pushing frequency ranges for emerging commercial systems upward to mm-wave frequencies as high as 86 GHz! Still, the bulk of near term 5G developments will likely be at the proposed bands of 28GHz and below.
