Product catalog summary
General Information
Radiall's Hi-Rel coaxial switches are specifically designed for space applications, boasting over 25 years of experience and deployment on more than 220 satellites. These switches are approved by the European Space Agency under specification ESCC3603. Radiall offers various models such as Engineering Model (EM), Qualification Model (QM), Proto Flight Model (PFM), and Flight Model (FM), providing cost-effective solutions for communication satellites.
Specifications
The operating temperature ranges from -30°C to +85°C, with non-operating temperatures from -40°C to +85°C. Vibration specifications include sinusoidal (5-100 Hz/20g) and random (20-2000 Hz/28.57 grms). Shock resistance is rated at 1200g for 0.25 ms. These switches are designed for free space vacuum environments.
Low Power Models
These models include SPDT, DPDT, T, and DP3T switches with SMA connectors supporting frequencies up to 31 GHz. Key specifications include actuation voltage (22-29V), actuation current, switching time, and RF performance metrics like insertion loss, VSWR, and isolation. Power handling is detailed with derating graphs considering multipactor and thermal dissipation.
High Power Models
High-power SPDT and DP3T switches are available with TNC connectors, supporting up to 4.8 GHz and power handling up to 160 Watts CW. Specifications include actuation voltage, current, switching time, and RF performance. Power handling is illustrated with derating graphs.
Radiall Specifications
Detailed specifications are provided for each switch type, including mechanical configurations, electrical characteristics, and RF performance. The document emphasizes the importance of consulting Radiall customer support for detailed technical information.
Specifications:
The document provides detailed specifications for high power coaxial T switches. Key parameters include actuation current at various temperatures, switching time, pulse duration, coil resistance, RF contact resistance, and coil isolation. The actuation current varies from 380 mA to 620 mA depending on the temperature. Switching time is 35 ms, and pulse duration ranges from 35 ms to 1000 ms. Coil resistance at +25°C is between 59.3 Ω and 61.8 Ω.
Electrical Characteristics:
RF contact resistance is 100 mΩ, and the TLM indicator circuit shows contact closed at 1000 mΩ and contact open at 1 MΩ. The contact current is 100 mA. Coil isolation at 500 VDC is 1 MΩ, and dielectric withstanding at 50 or 60Hz is 500 Vrms.
Mechanical Specifications:
The mass of the T-switch varies slightly between lay down and stand up configurations, approximately 355 to 360 grams. Torque specifications for screws are provided for fixing units and connectors, ranging from 0.44 N.m to 2.65 N.m.
RF Performance:
The frequency range is from DC to 8 GHz with insertion loss varying from 0.17 dB to 0.40 dB across different frequency bands. VSWR and return loss values are specified, with isolation minimum at 70 dB and E-field shielding effectiveness at a minimum of 70 dBi.
Product Variants and Part Numbers:
Various product models are listed with specific part numbers for different configurations, including SPDT, DPDT, T-Switch, and DP3T models. These are available in both low and high power variants with SMA and TNC connectors.
Additional Features:
The document mentions features such as telemetry circuits, suppression diodes, and options for D-Sub or solder pins. The switches are designed for space applications with high power handling capabilities.
Recommendations:
For more detailed technical information, consulting Radiall customer support is recommended.
