Q-Tech Corporation introduces its New Space Series temperature compensated crystal oscillators (TCXOs). Designed by the company’s German affiliate, AXTAL, these New Space Series devices, built with a modern TCXO IC, exhibit low phase noise, high-frequency stability and are fully TID and SEE radiation tested. Optimized for low earth orbit (LEO) satellite timing & frequency generation applications, they are offered in two industry-leading small footprint packages: AXLE5032S (5 x 3.2 mm) and AXLE7050S (7 x 5 mm). Testing and screening to specific customer requirements is offered and swept crystal versions are available.

Key features of the New Space Series are radiation tolerance to 50 kRad(Si) TID, single event latch-up immunity (tested up to 120 MeV-cm²/mg), selectable frequency stability (±1 to ±3 ppm) and phase noise floor of -160dBc/Hz (at ≥ 100 kHz offset). The TCXOs are packaged in hermetically sealed surface-mount ceramic enclosures to provide robust operation in mission-critical LEO environments.

“Today’s LEO 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. “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.”
