Fully Matched Cascadable Amp
The TQP3M9009 has been added to the company’s low noise gain block family for high performance 3G/4G infrastructure. This cascadable amplifier is fully matched internally, allowing designers to focus on system level needs. It operates over a broad .05 to 4 GHz frequency range.

Bandpass Filter
Part number 2965-SMA is a 500 MHz bandpass filter. The filter has a typical 1 dB bandwidth of 8 MHz, insertion loss of 6.5 dB and typical 40 dB bandwidth of 52 MHz. It is supplied in a 0.6 x 0.6 x 2.25" SMA package and may be customized for other center frequencies and bandwidths.

UltraFast™ Digitally Programmable LDO
The LT3071 is the second in a family of digitally programmable linear regulators with the lowest dropout voltage, lowest noise, and fastest transient response of any monolithic 5A LDO currently available. Dropout voltage at 5A is an ultralow 85mV. Its QFN package is 4 x 5 x 0.75mm in size.

Microwave Power MMIC
A 4W C-Band GaAs MMIC for satellite applications, the TMD0608-4 operates in the 5.65 to 8.50 GHz range. With this broad bandwidth, a high gain of 27 dB throughout the operating range, and 50 ohm internal matching, this device is well suited for use as a pre-amplifier in C-Band satellite and terrestrial communications.

USB Power Sensors
The U2000 Series USB-based power sensors are compact, portable solutions that allow average power measurements without power meters. All sensors, except the U2004A model, feature internal triggering and trace display capabilities. Current users of these sensors can upgrade their firmware for free.

Directional Couplers
Miniature air dielectric directional couplers are rugged, lightweight devices that offer lower insertion loss than comparable stripline units. The simplified construction allows for greater flexibility in creating customized configurations. Any port can be used as the input with these devices.

Elliptic Lowpass Filter
Part number 2969-SMA is a high order 10 MHz elliptic lowpass filter with sharp transition to the stopband and high stopband attenuation. Typical 1 dB bandwidth is 10.9 MHz with minimum 84 dB attenuation at 13.125 MHz. It is supplied in a 0.6 x 0.6 2.25" package with SMA connectors.

Directional Coupler
Model 110067016 directional coupler has a frequency range of 10 to 67 GHz, 7.25 directivity, and maximum VSWR (any port) of 2.0. Coupling (with respect to output) is 16 +/-1.1 dB and frequency sensitivity is +/-2.0 dB. Operating temperature range is -54 to +85ºC.

Fixed Frequency Synthesizer
The SFS6400A-LF in C-band is a single frequency synthesizer that operates at 6400 MHz. This synthesizer features a typical phase noise of -88 dBc/Hz @ 10 KHz offset and typical sideband spurs of -65 dBc. Its PLL-V12N package measures only 0.60 x 0.60 x 0.13".

Higher Power GaAs FETs
The company has expanded its Ku-Band GaAs FET lineup with two higher output power devices rated for 18 and 30W. Models TIM1213-18L and TIM1213-30L operate in the 12.7 to 13.2 GHz range and are targeted for use in microwave radios for microwave links and satellite communications.

EMT SMT Diode TVS Connectors
Now available are transient protection solutions embedded within the connector shell utilizing surface mount (SMT) diodes. Using SMT diode technology allows for increased flexibility in the packaging of transient protection within the connector, saving both space and weight.

Low Noise Gain Block
Model TQP3M9008 is a new low noise gain block that offers high gain over a broad .05 to 4 GHz frequency range. It is a cascadable amplifier that requires no external matching components and can reduce BOMs. The gain block provides 35.5 dBm OIP3, while maintaining a low 1.3 dB noise figure.

Scott N. Talbot
General Manager, EM Research, Inc.

Q: Given the current economic crisis affecting the U.S. – which will certainly have international repercussions – how do you think the markets you serve may be impacted? How do you and your company plan to address this?

A: The current global economic conditions and the results of the recent U.S. Presidential election will certainly play major roles in the future of the electronics and microwave industries. Our plan is to stay the course of building our customer base in all areas of the military and commercial complexes and to continue to respond to our customers’ needs. We will also maintain our efforts on developing new technology which will support new applications and emerging technologies.

Q: At the last MTT-S show, “LTE” was added to “WiMAX” as the killer app for 2009. Would you agree with this, or do you have something else in mind?

A: We agree that LTE is a very exciting expansion to the mobile network technology world. As with all new technology, it is important to continue to improve performance to be able to provide effective solutions at an extremely rapid pace. Our product lines are extremely agile and will easily be adaptable to most of these new technologies that utilize terrestrial radio access networks.

Q: What do you feel are the greatest opportunities for manufacturers in either the commercial or military markets?

A: Achieving wider bandwidths with better specifications in smaller and less expensive packages are important for all microwave component companies. Our next generation of products are available for both commercial and military markets. Recent additions like our CLX Series, offer excellent performance and improved depth to our surface-mount line. Improvements to existing products, such as our ESP Series, now with typical phase noise of <-143 dBc/Hz @ 100 KHz, operating at 1.1GHz, allow us to offer exceptional performance in robust designs.

Q: Which of the past year’s developments or emerging technologies has you most excited?

A: This compliments the response to Question 3; we are definitely excited about all the new projects for the multitude of applications being utilized on smaller platforms. These applications all require highly-sophisticated products that are orders of magnitude smaller and must meet the stringent environmental requirements of hi-rel products.

Q: How would you rate the health of the microwave industry as we near the end of the decade?

A: R & D projects and other new programs are still available, but the uncertainty in the economy may affect the ability of these projects to be able to transition into production. I had a discussion with an individual recently. His company designed a new widget that is passing all tests and field trials. It is exceeding all expectations, but the company’s funding is up in the air and they don’t know if and when they will be able to take this new product to market. However, I believe that companies will continue to use resources for R & D to develop the next generation of products and continue to push technology further so they are ready when the pendulum swings back.
