Teledyne HiRel Semiconductors, a leader in ruggedised semiconductors for mission-critical environments, announced the TDLNA0840EP, an ultra-low-power, wideband, low-noise amplifier (LNA) that delivers guaranteed operation to 4.0 GHz, while consuming only tens of milliwatts from a single 1.5-volt supply. With a typical gain of 29 dB and a typical noise figure of 1.5 dB across 0.3–4.0 GHz, the TDLNA0840EP enables significant power savings in space, avionics, and battery-constrained RF systems. The TDLNA0840EP is the lowest-power, 4 GHz low-noise amplifier on the market, delivering significant SWaP reductions compared to conventional solutions that require higher bias currents and voltages.
“Space, defense, and avionics programs are under constant pressure to reduce power budgets without compromising RF performance,” said Mont Taylor, Vice President of Business Development at Teledyne HiRel Semiconductors. “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.”
