Dow-Key® releases R521 high performance switch


Dow-Key® releases R521 high performance switch to The Reliant Switch™ product series – Your ATE Solution

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 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.
