Teledyne e2v HiRel extends space-qualified InGaP gain blocks to X-band

Teledyne e2v HiRel Electronics 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 announced availability of the new 14GHz family of RF gain blocks, spearheaded by an 18.4dB amplifier (TDGB014-003). The gain blocks are based on an indium gallium phosphide (InGaP) technology that is suitable for aerospace & defense applications because of its ceramic packaging and space qualification.

The gain blocks also come in gain configurations of 13.6dB and 16.5dB, allowing design engineers to exactly configure the signal gain without incurring unwanted parasitic effects.

Teledyne e2v HiRel says that, with its new family of X-band gain blocks, customers now have a standard amplifier solution that covers L-band through X-band. The standard amplifier enables a reduction in the number of new qualified components required for flight programs, simplifying the component procurement process.

The TDGB014-003 50Ω gain block utilizes a mature and reliable heterojunction bipolar transistor (HBT) InGaP process and incorporates proprietary monolithic microwave integrated circuit (MMIC) design techniques. The process has space-flight heritage and has shown to be radiation tolerant to 100krad, making it a viable choice for satellites and other high-altitude applications.

“Teledyne e2v HiRel has developed a broad portfolio of analog, digital, power and RF semiconductors targeted at aerospace & defense applications,” says Mont Taylor, VP of business development. “We’re pleased to be able to incorporate InGaP technology into our current A&D product offerings. Additionally, we are excited to provide a growing portfolio of standard RF building blocks such as amplifiers, LNAs, PAs, DSAs, limiters, mixers, pre-scalers, PLLs, switches and more to help customers design RF signal chains that meet the high-reliability requirements of defense and space.”

Teledyne e2v’s Hi-Rel X-band gain blocks offer what’s said to be high gain flatness and P1dB (output power at 1dB gain compression point). The 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.
