Teledyne HiRel Launches Space-Screened Low-Noise Amplifier for LEO and MEO Satellites

Teledyne HiRel Semiconductors, a business unit of Teledyne Technologies Incorporated (NYSE: TDY) and a leading supplier of high-reliability RF and microwave solutions, announced the TDLNA0840SEP, a space-screened, ultra-low-power, wideband low-noise amplifier (LNA) designed to support the growing demands of satellite constellations in low Earth orbit (LEO) and medium Earth orbit (MEO), spaceborne communications and advanced RF front-end architectures.

Building on the proven performance of the TDLNA0840 family, the TDLNA0840SEP delivers high-sensitivity signal reception in power- and space-constrained environments, improving system performance while reducing size, weight, and power (SWaP). Space-level screening simplifies qualification and helps lower program risk across mission-critical deployments.

Optimised for satellite payloads, phased arrays and telemetry systems, the amplifier provides consistent, low-noise performance across a wide frequency range, supporting next-generation communications and resilient space architectures at scale.

“Today’s space programs demand solutions that balance performance, power efficiency and reliability,” said Mont Taylor, Vice President of Business Development, Signal and Power Switching. “The TDLNA0840SEP enables high-performance RF front ends with simplified qualification and mission-ready reliability.”

TDLNA0840SEP Highlights

• Space-screened for mission-critical LEO and MEO applications
• Ultra-low-power operation enabling SWaP-efficient designs
• Wideband coverage from 0.3 to 4.0 GHz
