Teledyne e2v HiRel has developed a radiation tolerant S-Band low noise amplifier (LNA) for space and radar designs.

The TDLNA2050SEP LNA from Teledyne e2v HiRel is developed on a 90nm enhancement-mode pseudomorphic High Electron Mobility Transistor (pHEMT) process and 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 uses monolithic microwave integrated circuit (MMIC) design techniques for S-band communication applications. It 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.

“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,” said Mont Taylor, Vice President and Business Development Manager at Teledyne e2v HiRel.

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.

Devices are available for ordering and shipment today, from Teledyne e2v HiRel or an authorized distributor, in commercial versions and with the option of Classes H and K-equivalent screening. They are shipped from a DoD Trusted Facility in Milpitas, California.
