Temperature Variable Chip Attenuator

STATE OF THE ART, INC. INTRODUCES NEW A LINE OF TEMPERATURE
VARIABLE ATTENUATORS FOR RF AND MICROWAVE APPLICATIONS

State College, PA, SEPTEMBER 2012 -- State of the Art (SOTA), Inc., a leading manufacturer of military, space level and high reliability chip resistors, introduces a new line of temperature variable attenuator (TVA) for both high reliability and commercial applications.

Available in a 1512 case size (.150" X .125" X .020") with single surface solderable or wire bondable terminations.

The attenuation of these TVA's decrease with increasing temperature allowing the TVA to passively compensate for the amplifier's drop in gain with temperature.This kind of signal compensation can be used for various amplifiers (power amplifiers, low noise amplifiers, MMIC amplifiers, and gain block amplifiers),circulators, mixers, power dividers, and other temperature sensitive devices. TVA's have the added benefit of lower signal distortion, phase change, and intermodulation compared to active circuit temperature compensation.

These devices operate between DC and 6 GHz, with attenuation between 1-10 dB.
They are offered in three temperature coefficient of attenuation (TCA) values -0.003, - 0.007, and -0.009 dB/dB/C. The power handling capability is 2 watts with a 50 ohm load. High reliability and space screening is also available.

State of the Art Announces New Z Termination Thin Film Chip Resistors

State College, PA April 2012 - State of the Art, Inc. (SOTA) announces the offering of their Z termination line of miniature, high reliability chip resistors. Thin film single surface and wrap around designs.

The resistors range in size form 0402 (.040" X .020") to 2512 (.025" X .025"), with tolerances from 0.1%, power ratings from 50mW to 1500mW temperature coefficients of resistance as low as 25ppm, and voltage ratings from 30volts to 200V. The operating range for these resistors is from -55°C to + 125°C.
The Z Termination is a gold over nickel finish which can be attached with solder, conductive epoxy, or gold wire bonds. The Z termination resistors are a RoHS compliant product.

Reliability is assured by extensive in house testing - users can select from a wide variety of testing options. These include standard product, Mil-PRF 55342 established reliability (R or S level), or space level to Mil-PRF-55342 "T" product level. Custom testing to customer specifications is also available.

SOTA chip resistors are designed for use in a wide range of high reliability applications including medical electronics, defense systems, microwave communications, aerospace electronics, and satellite systems.

Pricing is generally under $1.50 in manufacturing quantities. Current lead time is 8 weeks, but SOTA maintains more than 50 million resistors in stock. Delivery on stock items is 2 business days ARO.

THIN FILM MIL-PRF-55342 TERMINATION VOIDS

State College, PA, March 2011 -- Three customers have reported a total of four thin film B termination material MIL-PRF-55342 devices exhibiting open circuit conditions after reflow solder mounting. All four devices were identified by routine electrical and visual inspection of the mounted devices. The assembly failures were reported on Feb. 5th 2009, August 31st 2010, Oct. 19th 2010, and February 14th 2011. No post assembly failures have been reported, nor have there been any life test failures. The thin film devices in question are identified by B termination material and either characteristic symbol E and H or resistance tolerance and multiplier symbols A, B, and C (0.1%).

As of January 17th 2011 all shipments of thin film MIL-PRF-55342 solderable devices have been screened to mitigate the shipment of potentially defective devices.

STATE OF THE ART INTRODUCES THE FILTENATOR

State College, PA, March 2011 -- State of the Art (SOTA), Inc., the leading manufacturer of mission critical military and high reliability resistive products, announces the addition of the Filtenator to its high frequency product line.

The Filtenator is a clean attenuator that uses an integrated filter to eliminate high frequency signals. The cut-off frequency can be varied between 5.5 and 8.5Ghz. Standard attenuation values are 1, 3, 6, and 10 dB. VSWR for all four values is less than 1.5:1, with attenuation tolerance less than +/- 1 dB. Measuring 0.150" x 0.120" x 0.015" these devices are available with wire bondable or solderable terminations.

The Filtenator chip design provides an advantage over fixed chip attenuators by filtering the high frequency harmonics, thus providing a cleaner signal. To make the concept transparent to existing chip attenuator users, the geometry of the Filtenator including the dimensions of the termination pads are kept identical to our standard 1512 attenuator.

Filtenators are manufactured at SOTA's ISO 9001 & AS9100 manufacturing facility located in State College, PA. Reliability is assured by SOTA's proven processes, and rigid quality controls. Customer specific applications can be accommodated, including optional high reliability screening or custom testing.

Pricing for the new components is under $1.90 in production quantities. Delivery is stock to eight weeks ARO.

STATE OF THE ART INTRODUCES NEW MULTI-TAP ATTENUATORS

State College, PA, October 2008 -- State of the Art (SOTA), Inc., the leading manufacturer of mission critical military and high reliability chip resistors, announces the addition of new multi-tap attenuators to its high frequency product line.

The MTA1225 (0.125" x 0.250" x 0.015") multi-tap attenuators are available with wire bondable or a solderable terminations. Constructed using a high stability thick film resistor element on alumina, these devices offer four standard attenuation values on a single chip. Standard attenuation values are 1, 3, 6, and 10 dB. VSWR for all four values is less than 1.5:1, with attenuation tolerance +/- 0.5dB or 10% whichever is greater, up to 1 GHz.

The multi-tap attenuator chip was designed to eliminate the use of multiple attenuator devices in attenuation switching functions, thus reducing board space and inventory costs. The MTA1225 is a single chip solution for low frequency multiple signal processing applications, providing multiple attenuation levels when used in conjunction with a high frequency switch or a pin diode.

Multi-tap attenuators are manufactured in the USA at SOTA's ISO 9001 manufacturing facility, where reliability is assured by SOTA's proven processes, and rigid quality controls. Customer specific applications can be accommodated, including optional high reliability screening or custom testing.

Pricing for the new components is under $1.90 in production quantities. Delivery is stock to eight weeks ARO.
