Comb Generator
The CG1000 series comb generator provides a combline of CW outputs up to 26 GHz. Picket sizes of 500, 750 and 1000 MHz are available, A TCXO, PLO and integrated amplifier are all included in the compact design. Frequency range is 1 to 18 GHz.

QFN Packaged Up-Converter
A 37 to 40 GHz GaAs MMIC up-converter, model XU1019-QH, integrates an image reject balanced mixer, LO buffer amplifier, LO doubler and RF buffer amplifier within a fully molded 4 x 4mm QFN package. It delivers +20 dBm IIP3 and 7 dB conversion gain.

RF Transformers & Diplex Filters
A family of CATV RF transformers and RF diplex filters meets DOCSIS 3.0 design requirements for applications such as set-top boxes, cable modems, and gateways, supporting frequency bands 5 to 65/85 to 1002 MHz, 5 to 42/54 to 1002 MHz, and 5 to 85/108 to 1002 MHz.


SMA Transfer Switches
New micro miniature SMA transfer switches incorporate SMA connectors to allow high-density packaging and excellent electrical performance through 26.5 GHz. The switch is available in failsafe and latching configurations with a choice of three frequency ranges and three coil voltages.

Bluetooth Low Energy Test Solution
Designers and manufacturers of Bluetooth® products can now use a new Bluetooth low energy testing option to conduct radio layer testing that is in compliance with the newly adopted Bluetooth Core Specification 4.0. With the option, engineers can use the MT8852B to complete a test script covering Bluetooth Basic Rate, EDR, and low energy measurements in <15 seconds by pressing a single key, greatly simplifying production test programs.

LTCC Bandpass Filter
The BFCN-2435+ LTCC bandpass filter is constructed with 12 layers in order to achieve a miniature size and high repeatability of performance. Covering 2435 MHz +/-95 MHz, these units offer low insertion loss and good rejection. Frequency range is 2340 to 2530 MHz.

Coaxial to Waveguide Adapters
Now available are coaxial to waveguide adapters in a variety of configurations. Option A are broadband adapters with excellent electrical specs maintained over the entire bandwidth. Option B offers enhanced performance over a specific band of the adapters’ bandwidth.

RoHS Compliant VCO
Model ZRO2300A1LF in S-band operates at 2285 to 2315 MHz with a tuning voltage range of 0.5 to 4.5 Vdc. It is designed to deliver a typical output power of 3 dBm at 5 Vdc supply while drawing 18 mA (typ.) over the temperature range of -40 to +85ºC.

Scalable Microwave Switching Solutions
Two new RF/microwave switching solutions, the EX7105A and EX7204A, are part of the EX7000 series. These high-density instruments have an open-platform COTS core that can be easily configured for a variety of custom applications.

LTCC Bandpass Filter
The BFCN-7900+ LTCC bandpass filter is constructed with five layers in order to achieve a miniature size and high repeatability of performance. Wrap-around terminations minimize variations in performance due to parasitics. Frequency range is 7800 to 8100 MHz.
 
Transient Capture and Timestamp Module
The EX1200-7416 is a transient capture and timestamp module that further extends the capabilities of the popular EX1200 series of configurable LXI Class A instruments. With a rich feature set, it supports a broad range of applications that require level comparison, event detection, and time stamping.


SPDT T/R Switch
The HMC784MS8GE is a low loss, high linearity GaAs pHEMT 10W SPDT MMIC switch for use in transmit/receive applications which require very low distortion at high input power levels. It can control signals from DC to 4 GHz and is housed in a MSOP-8G leaded package.

Greg Hindman
President, Nearfield Systems, Inc.

Q: Last year, we asked what kind of impact the worldwide economic crisis had on the markets you serve and on how you run your business under these conditions. One year later, what is your perspective?

A: At the beginning of the year with market uncertainties and worldwide media focus on a worsening economy, many experts predicted a significant drop in orders across the board. Almost a year later, here at Nearfield Systems, Inc. (NSI) orders and sales for Microwave antenna test and measurement products and services are holding up well. NSI has received increased interest in innovative and custom antenna test and measurement products. Many of our core customers and new antenna measurement customers are refurbishing or upgrading legacy test equipment and NSI offers innovative solutions to address this unique market.

Q: Do you think that spending for RF and microwave products will increase or decrease in the 2010 military budget?

A: Many people predicted the new administration would immediately reduce defense spending. As we know, procurement funding extends and overlaps administrative turnovers. Clearly, domestic spending is a priority now, but funding for an adequate defense – especially in the areas of communications - is important to the United States and its allies. NSI is aggressively pursuing antenna test and measurement opportunities within the US DoD and the international arena.

Q: There’s a serious shortage of RF engineers out there – what’s the solution? Is your company involved in any programs that might promote or encourage talented engineering students to concentrate on a career in the microwave industry?

A: For more than 20 years, NSI has supported AMTA, (Antenna Measurement Techniques Association), the international professional organization dedicated to the advancement of the state-of-the-art of antenna test and measurement. Each year, AMTA sets aside special technical, professional networking and social events at its annual symposium to encourage engineering students to consider careers in the Microwave industry. In addition, engineering students from all over the world are encouraged to submit technical papers to the AMTA symposium – the best of which are recognized with cash awards and free membership in AMTA. NSI wholly supports AMTA’s student focus as an essential element of its annual Symposium. NSI also encourages cooperation with academia and are actively collaborating with researchers on joint projects at the University of Ottawa, Canada, the University of London, UK and UCLA in Los Angeles.

Q: What do you feel is the greatest opportunity for manufacturers in either the commercial or military sectors?

A: Clearly, communications advancements in both the commercial and military sectors will drive manufacturers to produce antennas with advanced capabilities. For those of us in the test and measurement sector, two factors continue to drive new business: Innovation and Economy. Manufacturers and antenna users – both commercial and military – are driving the industry for faster and cheaper ways to test. NSI’s test and measurement software and ‘building-block’ component products, along with its advanced, in-house test and measurement facilities used by commercial and military customers, offer an attractive, economical solution for antenna test requirements. ♦
