Teledyne HiRel Semiconductors has introduced the TDLNA0840EP, an ultra-low-power, wideband low-noise amplifier (LNA) designed for mission-critical RF systems operating up to 4.0 GHz. The company states that the device delivers guaranteed performance across 0.3–4.0 GHz while consuming just 25–30 milliwatts from a single 1.5-volt supply, positioning it as the lowest-power 4 GHz LNA currently available on the market.
The TDLNA0840EP provides a typical gain of 29 dB and a typical noise figure of 1.5 dB across its operating bandwidth. By combining wideband coverage with minimal power consumption, the amplifier targets significant size, weight, and power (SWaP) reductions compared to conventional solutions that rely on higher bias currents and voltages.
According to Mont Taylor, Vice President of Business Development at Teledyne HiRel Semiconductors, space, defense, and avionics programs continue to face tightening power budgets while maintaining stringent RF performance requirements. He noted that the new device enables 4 GHz coverage at reduced power levels, potentially simplifying thermal management, extending mission life, and supporting higher-density module designs.
Housed in a compact 3 × 3 mm QFN package, the amplifier features internally matched, DC-blocked 50-ohm RF ports and supports operation across an extended temperature range of −55 °C to +125 °C.
The TDLNA0840EP is positioned for low Earth orbit (LEO) satellite payloads, phased-array systems, avionics, military communications, and battery-powered RF front ends where SWaP constraints are critical.
The device is available immediately, with evaluation boards and supporting documentation offered to accelerate system integration and qualification.
