Dow-Key® - 推出新的高性能产品线:1000万寿命循环RF开关,具有0.03 dB插入损耗重复性

R401k switch

陶氏钥匙® Microwave announces the release of its new high-performance product series called Reliant Switch™ with a SPDT being the first RF switch in this series made available to the RF & test industry.

工程师执行在电信系统集成munication and component manufacturing are faced with a range of challenges relating to the cost of test and the reliability over test systems’ life expectancy. RF tests across DUT’s require maintaining high insertion loss repeatability between ports to increase the measurement accuracy and reduce the source of errors in the measurement path. In addition, a longer life expectancy will keep the cost of replacing RF switches to a minimum thereby reducing the downtime and improving overall test efficiency. In addressing these challenges, Dow-Key® now offers a solution combining excellent electrical and mechanical performance over a broad frequency band with high isolation, low VSWR, long life, and exceptional insertion loss repeatability. 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.

Reliant Switch™SPDT具有15ms的开关时间,提供标称电源电压+ 12VDC或+ 24VDC的标称电源电压。可以通过施加接地来控制开关来关闭所需端口,但也可以通过TTL逻辑来控制(通过应用+ 5VDC关闭端口或+ 0VDC以打开端口)来控制。

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.

陶氏钥匙® 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.
