IN MY OPINION

Evaluating Our Industry’s Health Requires a Broad Perspective
By John Farley, Director of Marketing, Pasternack Enterprises

As most RF and microwave companies are privately held and industry analysts rarely track sales of microwave components other than semiconductors and interconnects, determining the health of an industry as diverse as ours is extremely difficult.

VIEW FROM THE TOP

AR

 

Q: Is there a particular emerging application or technology that intrigues you?

A: Yes, we believe AR is well positioned to excel in areas of EMC test equipment, RF Hybrid Modules, and RF amplifier systems. Applications for these products are growing at a significant pace due to the increased use of communication and control electronics which can cause electromagnetic interference. More specifically, we see opportunity within AR RF/Microwave Instrumentation for new higher power broadband amplifiers for various EMC and RF testing applications. We have also been using hybrid microelectronic technology in our designs which yield both higher frequency and broader band products in both wireless and TWT replacement markets.

AR Modular RF specializes in military communication products and is preparing to meet the demands of new Software Defined Radio’s (SDR) that have extended their frequency ranges up to 2GHz and carry complex and highly variable modulation schemes. This requires new designs with sophisticated switching and filtering schemes.

Q: Are you experiencing any effects of the reduction in defense spending or are you anticipating any impact on your business?

A: Even though some companies have concerns surrounding budgetary uncertainty, AR forecasted demand for our types of EMC instrumentation products has not decreased.
Our AR Modular RF Division which produces a higher percentage of military products has seen some softness but the radio communications arena where we participate has grown extremely important in recent years, with the complexity of communications traffic increasing as well. Originally communications was on a one to one basis, then a one to many, now it’s networking on an all too all basis, with huge jumps in the information exchange capacity capabilities of the radio equipment used. This drive for a bigger coverage area and faster data rates demands superior radio products that require our state of the art booster amplifier products.

Q: Deployment of small cells and distributed antenna systems is increasing rapidly as wireless carriers attempt to provide “broadband wireless data everywhere.” If your company is involved in any portion of the “HetNet” market, please tell us how you feel this market will develop.

A: AR is not directly involved in “HetNet” but manufactures products to test wireless components and systems with amplifiers providing up to 200 watts of Class A linear power over an instantaneous BW from .7 to 6 GHz.

Q: China has long been considered the greatest potential global market for many companies in the RF and microwave industry. Do you feel this is still true? Are there other emerging markets that you believe will be lucrative in the next few years?

A: AR is a global company that highly values the current customer base, strives to expand those relationships, and builds new relationships throughout the world. With that said, we believe Asia, and more specifically China remains a major market for AR RF/Microwave Instrumentation products. In addition, we are seeing excellent opportunities in the other BRIC countries.

The resurgence of the automotive industry, along with aerospace, and satellite industries are presenting many new opportunities. This truly is a global business.

Q: What do you believe will be the greatest challenge for the RF and microwave industry?

A: New and creative products are being developed at an incredible rate. Designing and manufacturing these state of the art products will require highly talented engineering people in circuit and system design. Finding these individuals is getting more difficult since a majority of engineering graduates are pursuing software related programs. From an RF technology point of view product sizes are shrinking and thus power density figures have reached all-time highs such that thermal engineering has become a major factor in the design of new equipment especially so for portable equipment.

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.
