ON THE MARKET


Band Reject Filter Series
Higher frequency band reject (notch) filters are designed to operate over the frequency range of .01 to 28 GHz. These filters are characterized by having the reverse properties of band pass filters and are offered in multiple topologies. Available in compact sizes.
RLC Electronics


SP6T RF Switch
JSW6-33DR+ is a medium power reflective SP6T RF switch, with reflective short on output ports in the off condition. Made using Silicon-on-Insulator process, it has very high IP3, a built-in CMOS driver and negative voltage generator.
Mini-Circuits


Group Delay Equalized Bandpass Filter
Part number 2903 is a group delayed equalized elliptic type bandpass filter that has a typical 1 dB bandwidth of 94 MHz and a typical 60 dB bandwidth of 171 MHz. Insertion loss is <2 dB and group delay variation from 110 to 170 MHz is <3nsec.
KR Electronics


Absorptive Low Pass Filter
Model AF9350 is a UHF, low pass filter that covers the 10 to 500 MHz band and has an average power rating of 400W CW. It incurs a rejection of 45 dB minimum at the 750 to 3000 MHz band, and power rating of 25W CW from 501 to 5000 MHz.

Innovation, The Silver Bullet
By Harvey Kaylie, President, Mini-Circuits

Liam Devlin, CEO, Plextek RF Integration

I believe American technology and competitive spirit has reawakened and is alive and kicking. Americans have always responded to challenges; the “can do” spirit is ingrained within our culture. Although we are still recovering from the “Economic Tsunami” of 2009, we are making progress and helping to lead the world back to economic growth.

Albert Einstein once said, “Scientists investigate that which already is; Engineers create that which has never been.” Engineering is leading the way to prosperity as it has from the time of Eli Whitney’s cotton gin, to the Wright brothers’ first flight of the Kitty Hawk, to Henry Ford’s model T automobile, to the introduction of the internet, and today with Elon Musk’s electric car, commercial satellites, and to fracking technology for getting oil from shale rock. In fact, the U.S. may even become an exporter of oil!

The head of the U.S. Patent office in 1906 made the statement, “I guess we have invented all there is to invent.” Some people may think that statement is valid today. I don’t think so. Far from it, we are continuing the surge to introduce new products and services. Consider the potentials and opportunities of utilizing white space, 3D printing, unmanned aerial vehicles, etc.

So what are the seeds that stimulate our creative juices and provide new products and services to advance mankind? At Mini-Circuits, as in many top tier technology companies, innovation, creativity, and multi-discipline team-building is being encouraged and supported. A company cannot simply say “I want creativity and innovation,” but rather management must clearly define the company’s vision and values, provide resources, a supportive environment, focus the team and establish metrics to measure the results of its innovation investment.

There are many areas in our industry where opportunities for growth can be powered by innovation. In general, these areas should focus on increasing value to the customer. So how do we increase value? It can be through technical innovation, manufacturing innovation, design for long life reliability, along with the ‘soft’ attributes that make one’s life easier including, design robustness, user-friendly software, process simplification, and product support for the entire lifetime of customer need.

One well-known product that exemplifies the economic prosperity resulting from innovation is Apple’s iPhone. It has had a powerful influence on our everyday living habits and created a new paradigm in the market for mobile computing and communications technology. At Mini-Circuits, we have embraced similar innovative concepts that change the way people in our industry work. Just recently, we were awarded a patent for a simple, easy to use Harmonic Calculator. This calculator can be a great tool for a receiver-system designer. It enables the selection of the LO frequency that would minimize the effects of unwanted harmonics providing more economical receiver design solutions as well as higher levels of receiver performance. This tool will even predict the levels of unwanted harmonic signals within the IF pass band of a receiver using real data from our Yoni search engine.

Another example of Mini-Circuits’ innovative solutions that provide value to our customers is through the introduction of our programmable mechanical switch matrices. These products are based upon our “nearly ideal” switches covering DC to 18 GHz with almost no insertion loss and very high isolation and enable long life reliability of more than 10 to 100 times better than others in the marketplace. The technology for these switches was invented by replacing mechanical springs, the major cause of failure, with magnetic controls and has been part of Mini-Circuits product offering for some time. However, the recent innovation of integrating these switches with USB and/or Ethernet control has enabled customers to realize and implement quick, easy to configure automated tests solutions. This new and unique adaptation of an existing technology was born out of our company’s vision and values; our engineering team captured the spirit of this vision and developed a product that is quickly becoming a universal enabler in automating complicated test applications.

It is often said that “necessity is the mother of invention.” Look for areas of improvement in your sphere of living, working, playing, or relaxing. Then ask yourself “what if?” and you’ll be on the road to innovation.

Uncertain Times for DefenseWill OpenRFM Shake Up the Microwave Industry?
By Barry Manz

Throughout the history of the RF and microwave industry there has never been a form factor standardizing the electromechanical, software, control plane, and thermal interfaces used by integrated microwave assemblies (IMAs) employed in defense systems. Rather, every system has been built to meet the requirements of a specific system, which may be but probably isn’t compatible with any other system. It’s simply the way the industry has always responded to requests from subcontractors that in turn must meet the physical, electrical, and RF requirements of prime contractors. Read More...
