You Need a High Reliable RF Switch? Dow-Key's Reliant Switch™!

As an engineer performing system integrations in telecommunication and component manufacturing, you are faced with a range of challenges relating to the cost of test, and reliability over the test systems' life expectancy. A longer life expectancy will keep costs of replacing RF switches to a minimum.
Herewith greatly reducing downtime and improving overall testing efficiency. 

 

    Dow-Key® - Reliant Switch™

  • Dow-Key’s® new Reliant Switch™ product line combines excellent electrical and mechanical performance over a broad frequency band with high isolation, Low VSWR, long life, and exceptional insertion loss repeatability. A Reliant Switch™ SPDT can sustain a guaranteed insertion loss repeatability of 0.03 dB across the entire frequency band from DC to 26 GHz. It also has an extended life where each position can switch a minimum of 10 Million cycles, which is a 10X improvement over a typical RF switch.

  • Example Specifications

  • The R521-series 1x2 bidirectional coaxial switch with an operating frequency range from DC to 26.5 GHz, covers the typical 6 GHz test frequency for high-speed testing. It is designed with a high isolation of 85 dB at 4 GHz and no less than 60 dB at 26.5 GHz, for maintaining the integrity of the measured signal in port-to-port testing. Each RF port of the SPDT switch will internally be terminated to a 2W 50-ohm termination when not in operation; making it your ideal switch for routing and testing WLANs, WiMAX LTE/4G/5G networks and separating signal sources in multi-band receiver/transmitter antenna applications.

  • Connectability & Operability

  • Reliant Switches™ are offered with latching actuators, optical position indicators and SMA connectors. The 1x2 switch operates in break-before-make mode with 150W CW input power at 3 GHz (cold-switching). In hot-switching applications, a maximum of 2W CW can be applied to the input port(s) across the frequency band. Switching times of 15ms are offered with a nominal power supply voltages of +12Vdc or +24Vdc. The switch can be controlled by applying ground to close the desired port, but it is also available to be controlled via TTL logic (by applying +5vdc to close a port or +0Vdc to open a port). Reliant Switch™ SPDT switch options can operate over a -25°C to +75°C temperature range and be stored between -55°C to +85°C. For antenna and radar related applications, the switch operates up to 15,000 ft. and can be stored at 50,000 ft. without any performance degradation.
