IN MY OPINION

Time to Reevaluate RF and Microwave Power Application Development

By Dan Viza, RF and Emerging Markets Manager Freescale Semiconductor

The methods for evaluating RF power components for use in RF and microwave applications have seen relatively little change over the years in spite of the expanding universe of RF applications.

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.
Werlatone


LTE Band 14 Ceramic Duplexer
This high performance LTE ceramic duplexer was designed and built for use in public safety communication and commercial cellular applications. It operates in Band 14 and offers low insertion loss and high isolation to enable clear communications in the LTE network.

President & CEO, Centellax, Inc.

Q: The importance of sustaining and developing technology has reached a point where states and cities are more actively building relationships with universities and recruiting high-tech companies. However, there continues to be a shortage of engineering graduates, especially those focusing on RF and microwave technology. What would your company do (or is doing) to help promote careers?

A: We do not have a specific program to address this issue, but we usually make available a couple of summer internships for students pursuing careers in the RF and microwave fields. We believe that this type of experience makes the student more aware of the career opportunities and the technical challenges available in this field.

Q: For those of you serving the military market, what do you expect 2013 will bring in terms of opportunities in this sector?

A: I expect that the military markets will demand features in common with the commercial markets like reduced cost, improved power dissipation and more integration of functionality for smaller form factors in assemblies.

Q: If your company serves the commercial markets, are you encouraged by any particular emerging application or technology?

A: The use of more complex technology will be required to meet the demands of new communications systems. SiGe and CMOS can bring out products that can meet seemingly contradictory specs like lower power dissipation with higher linearity. The use of AGC and other integrated features will be required from the rf transmitter in order to meet the system specs.

Q: Last year, we asked what impact the global economic crisis was having on the markets you serve and on how you run your business. What is your current perspective?

A: The global economic crisis allowed us to focus on improving and expanding our key core competences to create differentiating products from those of our competitors and thus provide our customers with a lower cost/higher performance solution. Strengthening and expanding core competences translate into an edge advantage that our customers value and recognize when we can offer the technology they need in a timely fashion.

Q: What countries or regions do you believe will provide the greatest growth potential for the wireless industry in 2013?

A: The wireless industry will continue a strong growth in North America and Asia Pacific Countries. China of course will be a strong playground for this and other communication technologies. ♦

FROM WHERE WE SIT

Uncertain Times for DefenseIn Defense of DARPA; Lamenting Bell Labs
By Barry Manz

A federal agency like DARPA is a sitting duck for politicians and assorted other critics. It has come up with some truly bizarre programs over years that ultimately either delivered no tangible results, were canceled before they could cause any damage, or attempted to answer questions that nobody was asking or needed answers to.
