Teledyne e2v HiRel announced the availability of a rad-tolerant S-Band low noise amplifier (LNA), model TDLNA2050SEP, that is ideal for use in demanding high reliability, space and radar applications where low noise figure, minimal power consumption and small package footprint are critical to mission success. This new LNA, developed on a 90 nm enhancement-mode pseudomorphic high electron mobility transistor (pHEMT) process, is available in an 8-pin dual-flat no-lead (DFN) 2 mm x 2 mm x 0.75 mm plastic surface mount package, and is qualified per MIL‑PRF‑38534 Class K.

The TDLNA2050SEP LNA leverages MMIC design techniques that deliver exceptional performance in the S-Band communication channel. The TDLNA2050SEP amplifier delivers a gain of 17.5 dB from 2 GHz to 5 GHz while maintaining a noise figure of less than 0.4 dB and an output power (P1dB) of 19.5 dBm. The device should be biased at a VDD of +5.0 volts and IDDQ of 60 mA and an evaluation kit is also available for customer evaluation.

“Today, we’re releasing our latest LNA, optimized for space and radar applications,” said Mont Taylor, vice president and business development manager at Teledyne e2v HiRel. “With a noise figure of less than 0.4 dB coupled with ease of use from a positive single supply voltage, we believe this new product will provide system designers with a superior solution for both space-based communication, phased array radar and communications system applications.”

The TDLNA2050SEP is TID radiation tolerant to 100 krad (Si), making it an excellent choice for satellite communication systems by increasing the power of radio signals with minimal noise and distortion which can degrade digital signals.
