Teledyne e2v HiRel launches line of 10GHz InGaP gain blocks for X-band
Teledyne e2v HiRel of Milpitas, CA, USA (part of the Teledyne Defense Electronics Group that provides solutions, sub-systems and components to the space, transportation, defense and industrial markets) has launched a family of 10GHz RF gain blocks using space-qualified indium gallium phosphide (InGaP) amplifier technology.
Spearheaded by an 18.4dB gain model, the TDGB010 series of gain blocks is based on InGaP technology suitable for both space and, optionally, defense flight applications. It achieves this through its ceramic packaging and space qualification.
Customers now access a standard amplifier solution that spans from L-band through X-band. Since a standardized amplifier solution reduces the number of new qualified components that flight programs typically require, it greatly simplifies the procurement process for components, notes the firm. The X-band gain blocks are available in configurations of 13.6dB, 16.5dB and 18.4dB, enabling RF design engineers to more precisely configure the signal gain.
The TDGB010 50Ω gain block incorporates proprietary monolithic microwave integrated circuit (MMIC) design techniques and also utilizes a mature and reliable heterojunction bipolar transistor (HBT) InGaP process. With space-flight heritage, the process has shown to be radiation tolerant to 100krad, making it an viable choice for satellites and other high-altitude applications.
“Our ongoing expansion of RF offerings is designed to help our customers produce high-reliability signal chains for the most demanding defense and space environments,” says Mont Taylor, VP of business development. “Our new gain blocks offer excellent gain flatness and high P1dB [output power at 1dB gain compression point],” he adds.
Teledyne e2v’s Hi-Rel X-band gain block family is available now, packaged in a 2-lead, ultra-small, hermetic gullwing package. Both the wafer process technology and the package have space-flight heritage.
