Rakon releases the radiation tolerant COTS XO RK105 and VCXO RK205
In order to respond to the growing needs of the New Space market (Low Earth Orbit satellites with a short mission lifetime), Rakon has recently released a radiation tolerant XO and a radiation tolerant VCXO, both based on a COTS (Commercially Off The Shelf) design.
They have been designed for missions requiring radiation tolerance at a reasonable cost and with a short lead-time: TID (Total Ionizing Dose) spec is 72 or 100 kRad (for CMOS) and Single Event Latch-up is guaranteed up to 32.4 or 62 MeV (for LVPECL).
Key features of these radiation tolerant COTS XO and VCXO also include:
• Wide frequency ranges with three output options available:
› CMOS output – Frequencies from 8 to 200 MHz
› LVPECL/LVDS output – Frequencies from 8 to 1500 MHz
• Tight FvT stability:
› AFD (Absolute Frequency Drift): ±50 ppm over -40°C to +85°C
› APR (Absolute Pulling Range): ±50 ppm for a VCXO
• Small hermetically sealed SMD package size of 5.0 x 3.2 x 1.2 mm
• Excellent high shock resistance: up to 1500 g, 0.5 ms, 1/2 sine
• Low RMS jitter: 0.9 ps typ.
• Low power: 50 to 178 mW typ.
Both products are available with different types of screening: from EM (Engineering Model) to FM (Flight Models), with 3 possible screening options for the FM in order to precisely fit the various requirements of the New Space projects. The COTS design of these both products make them cost-effective and ideal for the small LEO (Low Earth Orbit) satellites requiring radiation tolerant components at a reasonable cost.
