A low-noise amplifier is an electronic component that boosts very weak radio or sensor signals while adding as little extra electronic interference as possible, typically placed at the front of communication, radar, satellite and sensor systems. For investors it matters because better signal sensitivity and clarity can make a device more competitive—like a quieter microphone that hears faint sounds—impacting product performance, market appeal, pricing and revenue potential.
lnatechnical
Locked nucleic acid (LNA) is a chemical modification of the building blocks of RNA that makes short genetic probes or drug-like molecules bind more tightly and resist breakdown in the body. Think of it as adding structural “brace” to a fragile thread so it holds its shape and sticks to its target more reliably. For investors, LNA can improve the potency, durability and diagnostic accuracy of RNA-based therapies and tests, which can shorten development time, lower doses, and increase commercial value.
widebandtechnical
Wideband describes a communications signal, technology, or radio frequency allocation that uses a much larger range of frequencies than traditional (narrowband) systems. Think of it as a wider highway that lets more data travel at once, enabling faster connections, clearer transmissions, or more simultaneous users. For investors, wideband capability can mean competitive product advantages, higher service capacity, different regulatory or spectrum costs, and potential for greater revenue growth.
swaptechnical
A swap is a private contract where two parties agree to exchange streams of payments over time, often tied to interest rates, currencies, or commodity prices. Investors and companies use swaps to change the type of risk they face—like switching a variable-rate loan into a fixed one—so they can stabilize cash flow or gain exposure without buying or selling the underlying asset; think of it as trading the terms of future bills with another party.
qfn packagetechnical
A QFN package is a compact, flat housing for an electronic chip that has no outward pins and makes electrical and thermal contact through pads on its underside—think of it as a postage-stamp wrapper with a metal floor that connects directly to a circuit board. It matters to investors because the package affects product size, heat control, manufacturing cost and yield, and therefore can influence a device maker’s performance, reliability and supply-chain economics.
phased-arraytechnical
A phased-array is a sensor or antenna made from many small emitters or receivers whose signals are timed and combined so the overall beam can be steered and focused electronically without moving parts. Think of it like a crowd doing a wave: by changing when each person stands, the direction and shape of the wave changes. Investors care because phased-array designs can improve performance, reduce mechanical complexity, enable new products (in imaging, radar or wireless), and create competitive and regulatory advantages that affect revenue and costs.
rf front endstechnical
RF front ends are the group of electronic components in wireless devices that send and receive radio signals, including antennas, amplifiers, filters and switches. Think of them as the mouth, ears and throat of a phone or wireless modem that shape and boost signals before they reach the main processor; their performance affects connection quality, battery life and compatibility with networks, so investors watch them as indicators of product competitiveness and margins.
New ultra-efficient LNA delivers full 4 GHz performance at breakthrough power levels
GARLAND, Texas--(BUSINESS WIRE)--
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.
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.”
TDLNA0840EP Highlights
Lowest-power 4 GHz, wideband LNA on the market
0.3–4.0 GHz frequency coverage
1.5 V single-supply operation
