TCXOs target new space

Q-Tech Corp. has introduced its New Space Series of temperature compensated crystal oscillators (TCXOs). The new TCXOs, designed by the company’s German affiliate, AXTAL, offer low phase noise and high-frequency stability and are fully TID and SEE radiation tested.

The TCXOs are optimized for low-earth orbit (LEO) satellite timing and frequency generation applications. Key features include radiation tolerance to 50 kRad (Si) TID, single event latch-up (SEL) immunity (tested up to 120 MeV-cm²/mg), selectable frequency stability (±1 to ±3 ppm) and phase noise floor of -160 dBc/Hz (at ≥100 kHz offset).

The New Space devices are offered in two small packages: the AXLE5032S in a 5 × 3.2-mm footprint and the AXLE7050S in a 7 × 5 mm package. Testing and screening are available for specific customer requirements and swept crystal versions are available.

“Today’s low-earth orbit applications require lower-cost New Space products that offer proven state-of-the-art performance and known radiation hardness,” said Henry Halang, AXTAL’s managing director, in a statement. “The AXTAL New Space Series TCXO’s noise and stability features are optimized to meet all mission-critical specifications. Plus, they offer a unique benefit–their industry-leading small package sizes.”

The TCXOs are packaged in hermetically sealed surface-mount ceramic enclosures. They are available now.
