The miniature sized enclosure can be populated on the front panel with maximum of:

• (8) SPDT Reliant Switches™
• (2) SP6T Reliant Switches™
• (1) SP6T + (4) SPDT Reliant Switches™
• (2) SP6T + (1) SPDT Reliant Switches™

The MMS-series needs 12Vdc power supply and the switches can be controlled remotely via TCP/IP Ethernet and HTTP-Server, which has a built-in “Sequencer” feature that allows the user to program up to ten 500-step sequence programs.

No RF cables are provided with this solution.

The first release of Reliant Switch™ product line is a 1×2 bidirectional coaxial switch with an operating frequency range from DC to 26.5 GHz covering the typical 6 GHz test frequency for high-speed testing. The switch is designed with a high isolation of 85 dB at 4 GHz maintaining the integrity of the measured signal in port-to-port testing. The 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.

To meet a variety of test & measurement setups and signal switching configurations, the Reliant Switch™ is offered with latching actuators, optical position indicators and SMA connectors. The 1×2 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.

The Reliant Switch™ SPDT has a switching time of 15 ms and it is 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).

Both 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.

Dow-Key® Microwave’s new Reliant Switch™ product line is economically priced to minimize impact to budgetary concerns and are designed to deliver its specified performance over the life of the switch. Customers now have the flexibility to choose between life expectancy and cost without sacrificing switch performance.

Dow-Key® Microwave introduces a new switch product to their high performance product series called Reliant Switch™; a terminated SPDT switch available with or without TTL control is entering the market. The Reliant Switch™ product line is economically priced to minimize impact to budgetary concerns and are designed to deliver its specified performance over the life of the switch. Customers now have the flexibility to choose between life expectancy and cost without sacrificing switch performance.

The addition to the Reliant Switch™ product line is the R521-series bidirectional 1×2 terminated coaxial switch. Each RF port of the SPDT switch will internally be terminated to a 2W 50-ohm termination when not in operation; making it an ideal switch for routing and testing WLANs, WiMAX LTE/4G/5G networks and separating signal sources in multi-band receiver/transmitter antenna applications operating from DC up 26.5 GHz. The switch has successfully been tested to sustain a guaranteed insertion loss repeatability of 0.03 dB across the entire frequency band and outperformed an extended life with a minimum of 10 Million cycles per switch position, which is a 10X improvement over a typical SPDT switch.

Covering DC to 26.5 GHz, the bidirectional coaxial switch has a maximum insertion loss of 0.42 dB up to 4 GHz and 0.80 dB at 26.5 GHz and the repeatability of the insertion loss is guaranteed to be 0.03 dB across the entire operating band. The design offers a low VSWR: 1.15:1 up to 4 GHz and 1.50:1 at 26.5 GHz. Further, the switch is designed with a high isolation: 85 dB at 4 GHz and no less than 60 dB at 26.5 GHz. To meet a variety of test & measurement setups and signal switching configurations, the Reliant Switch™ is offered with latching self cut-off actuators, optical position indicators and SMA connectors. The terminated SPDT R521K-series switch operates in break-before-make mode and handles 150 W CW input power at 3 GHz.

The Reliant Switch™ R521-series terminated SPDT, has a switching time of 15 ms and it is offered with a nominal power supply voltages of +12 Vdc or +24 Vdc. The switch can be controlled by applying ground to close the desired RF port, but it is also available to be controlled via TTL logic (by applying +5 Vdc to close a port or +0 Vdc to open a port).

The Reliant Switch™ R521K-series switch operates over a -25°C to +75°C temperature range and can 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.
