Teledyne e2v HiRel releases enhanced plastic UHF to S-band ultra-low-power LNA for space applications
Teledyne e2v HiRel Electronics of Milpitas, CA, USA (part of the Teledyne Defense Electronics Group that provides solutions, sub-systems and components to the space, transportation, defense and industrial markets) has announced the availability of its latest space-enhanced plastic (SEP) UHF to S-band (0.3–4GHz), low-noise amplifier (LNA) model TDLNA0840SEP, which is suitable for demanding high-reliability applications where ultra-low power consumption, low noise figure, and small package footprint are critical for program success.
This LNA, developed on a 150nm enhancement-mode pseudomorphic high-electron-mobility transistor (pHEMT) process, is available in a 16-pin quad-flat no-lead (QFN) 3mm x 3mm x 0.90mm plastic surface-mount package.
The LNA leverages monolithic microwave integrated circuit (MMIC) design techniques and delivers what is claimed to be exceptional performance. The TDLNA0840SEP amplifier is suitable for UHF to S-band communications and consumes just 27mW of power while delivering a gain of 29dB from 0.3GHz to 4GHz and maintaining a noise figure of less than 2dB and an input P1dB of –35dBm. It is internally self-biased using VDD = +1.5V and IDDQ = 17.8mA typical. No external bias resistor is required.
A customer evaluation kit is available for this LNA, which is a suitable choice for satellite communication systems featuring increased power of radio signals with minimal noise and distortion which can degrade digital signals.
The TDLNA0840SEP is TID radiation tolerant to 100krad (Si) and is qualified per Teledyne’s space-enhanced plastic flow. It is available for sampling in third-quarter 2024 and will be available for shipment from the firm’s DoD Trusted Facility in December.
“With a power consumption of only 27mW, coupled with a flat gain-slope response of 29dB from 0.3GHz to 4.0GHz, we believe this new LNA will provide system designers with a superior solution for phased-array communications and system applications where minimal power consumption is critical,” says Mont Taylor, VP & business development manager.
