New ultra-efficient LNA delivers full 4 GHz performance at breakthrough power levels

Teledyne HiRel Semiconductors, a leader in ruggedized semiconductors for mission-critical environments, today 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.
