Teledyne HiRel Semiconductors Launches World’s Most Efficient 4 GHz Wideband LNA

Key Takeaways

Teledyne HiRel Semiconductors launched the TDLNA0840EP, an ultra-low-power LNA operational up to 4.0 GHz.
The device provides a typical gain of 29 dB and consumes only 25 to 30 mW at a 1.5 V supply.
Target applications include spaceborne receivers, avionics, and battery-constrained RF systems.

Product Overview

Teledyne HiRel Semiconductors has announced the release of the TDLNA0840EP, a cutting-edge low-noise amplifier (LNA) designed for ultra-low power consumption and wideband operation. This LNA guarantees functionality up to 4.0 GHz while drawing only tens of milliwatts from a single 1.5 V power supply.

With a typical gain of 29 dB and a noise figure of 1.5 dB across the frequency range of 0.3 to 4.0 GHz, the TDLNA0840EP presents a significant advancement in efficiency for applications in space, avionics, and other RF systems that require minimal power. Marked as the lowest-power 4 GHz LNA available, this device offers substantial size, weight, and power (SWaP) reductions compared to traditional solutions that require higher bias currents and voltages.

Mont Taylor, the vice president of Business Development at Teledyne HiRel Semiconductors, emphasized the challenges faced by sectors such as space, defense, and avionics, where there is a persistent demand to lower power budgets while maintaining high RF performance. He noted, “With the TDLNA0840EP, customers can achieve true 4 GHz, wideband coverage at breakthrough power levels, thereby simplifying thermal design, extending mission life, and enabling denser arrays and modules.”

Key Features

The TDLNA0840EP offers several notable features:
– It operates across a frequency range from 0.3 to 4.0 GHz.
– The device runs on a 1.5 V single-supply operation with power consumption typically between 25 to 30 mW.
– It boasts a compact size of 3 × 3 mm in a QFN package with internally matched, DC-blocked 50 Ohm RF ports.
– The LNA is equipped to function within an operating temperature range of −55 °C to +125 °C.

Applications

The TDLNA0840EP is ideally suited for various applications, including:
– Low Earth Orbit (LEO) satellite payloads and spaceborne receivers where efficiency is paramount.
– Phased-array and active antenna elements used in advanced communication systems.
– Avionics and military communication systems that prioritize small form factors and energy efficiency.
– SWaP-constrained settings and battery-powered RF front ends, critical in today’s increasingly portable electronic environments.
