Teledyne e2v HiRel announced the availability of radiation tolerant RF and Power products for the evolving New Space market. Qualified based on the EEE-INST-002 space grade standard, these plastic packaged products are qualified for the harsh environment of space with –55°C to +125°C temperature operating ratings, and are radiation tolerant for use in LEO, MEO, and GEO missions.

The RF products include several low noise amplifiers (LNA) and are ideal for demanding high-reliability space applications where low noise figure, minimal power consumption, and small footprint are critical to mission success. They are ideally suited for satellite communication systems that are increasing the power of radio signals so utilizing components with minimal noise and distortion help minimizing the degradation of digital signals.

These LNAs are developed in the radiation tolerant pHEMT technology semiconductor process technology. The monolithic microwave integrated circuit (MMIC) products are available in dual-flat no lead (DFN) plastic over molded SMT packages and are biased over single positive VDD supply voltages, eliminating the need for negative power rail voltages.

  • The TDLNA002093SEP delivers a low noise figure of less than 0.37 dB, IDDQ from 30 mA to 100mA, and exceptional performance from 1 GHz (L-band) to 6 GHz (S-band) frequencies.
  • The TDLNA0430SEP delivers an industry leading low noise figure of less than 0.35 dB, IDDQ of 60mA and exceptional performance from 0.3 GHz (UHF) to 3 GHz (S-band) frequencies.
  • The TDLNA2050SEP delivers an industry leading low noise figure of less than 0.4 dB, IDDQ of 60mA and exceptional performance from 2.0 GHz (S-band) to 5 GHz (C-band) frequencies.

The Power products offerings include Gallium Nitride (GaN) technology High Electron Mobility Transistors up to 650V, currents up to 90 Amp, high switching frequencies, and low RDSON. These GaN solutions have easy gate-drive requirements and enable high power density designs with four times less space requirements than traditional MOSFETs. The TDG650E60xSP parts are available in extremely small non hermetic packages with either top-side and bottom-side thermal pads and are ideally suited for satellite power supply systems with space production screening.

“Today we’re announcing our New Space products offering of RF and Power products optimized for space applications,” said Mont Taylor, Vice President and Business Development Manager at Teledyne e2v HiRel. “These LNAs with their ultra low noise figures coupled with the high power density capabilities of GaN transistors, we believe these products will enable system designers with superior solutions for space based satellite communication applications.”
