Dow-Key Microwave Corporation, the world leader in electromechanical switches, has been providing Low PIM rated coaxial switches to its customers for few years. Today, Dow-Key is excited to announce the next series of Low PIM switches now available with N-type connectors (in addition to SMA connectors) for both the RF Test and Wireless Communication industries. 
Today, a growing demand on wireless communication devices and RF systems require passive intermodulation (PIM) to be carefully considered as we push for higher data rates, larger wireless coverage area and system reliability.
PIM is a concern at the wireless system level because intermodulation products from an adjacent transmit bands appear in the receive bands raising the receiver noise floor. System performance is reduced and the wireless system as a whole becomes less reliable without a Low PIM Coaxial Switches. With Low PIM coaxial switches rated at -160 dBc, the choice can make a big difference on the RF and Wireless Communication testing outcomes.
In order to reach higher levels of performance, the non-linear response to RF signals from passive devices like switches and their connectors must be minimized so that system performance robbing intermodulation products are not produced. With Dow-Key’s New line of Low PIM Coaxial Switches, the results will be supported by the industries best switches test after test.
Dow-Key Low PIM switches offer the solution required to minimize intermodulation. Now SPDT, DPDT and SP6T with SMA or N-type connectors are available in the New Low PIM Coaxial Switches from Dow-Key Microwave. These Low switches are specifically designed and guaranteed to meet 3rd order IM requirements below -160 dBc; at 1870 MHz and at approximately +43 dBm with carrier frequencies 1930 MHz and 1990 MHz.
Adolf Cheung, Dow Key Microwave’s Sales and Marketing stated, “As a technology leader, Dow-Key remains committed to deliver innovative switching solutions for the RF Test and Measurement market, including the Wireless Communications industry.” Cheung also added, “The extensive qualification, along with the refinement of our manufacturing process for our latest Low Passive Intermodulation (PIM) switches, has enabled Dow-Key to build a solid foundation focused on the cutting edge of technology, and in areas directly in line with our customers’ needs. With this new offering of Low PIM Coaxial Switches, we have specifically target the RF Test and Wireless Communication industry’s needs.”

Dow-Key Microwave Corp. Offers New Matrix Platform
August 3, 2012 at 4:40 pm | Posted in Uncategorized | Leave a commentBy Offering the Advanced MP-Series of Multiplexers, Dow-Key Gives Users More Control in Performing Switching and RF Testing
Dow-Key, the world’s largest manufacturer of electromechanical switches for radio frequency and microwave applications, is thrilled to highlight another full featured product, the MP-Series Bidirectional Switch Multiplexer. A device that routes one input to various outputs, the Multiplexer now gives users a more convenient platform than before.
“The feedback from our customers for all of the features have been very positive as we have listened to their needs and responded back with a convenient platform that gives users more control…which is the way it should be,” said Sara Nazemzadeh.
The MP-Multiplexer features a drastically higher switching speed from the previous model. With 50 ms the user can command the switch to change position, reducing testing time when the user creates automated tests. This model keeps the cycle count of each position in every switch, and since coxial switches have limited life, this helps users track it.
The user also has full control of adding and removing switches, whether it is for replacing the unit with a new switch or adding additional switches to the matrix. “This is a benefit to the customer as they no longer need to return the unit to us to have it serviced or upgraded…they can do it themselves,” said Nazemzadeh.
Another interesting update is seen in the Ethernet model extending its use to include built-in webpage access so the user can control the matrix from any web browser with assigning both static dynamic IP addressing. Further, the matrix can also be controlled via USB port. Dow-Key SCPI commands are available to allow the use to not only control the matrix remotely but to also be embedded in end-user automated software test programs.
The feedback has been overwhelmingly positive on both the software and hardware updates. Nazemzadeh said that “the entire brain of the system resided on a tray, which can be easily removed from the rear. It allows the user for trouble free maintenance for field upgrades and repair.” If required, redundant power supplies, fans, and temperature sensors can be added to the unit as well.
Dow-Key, founded in 1945, and headquartered in Ventura, CA, is the oldest continuously operating RF/microwave switch manufacturer in the United States. Dow-Key has also been developing matrix switch solutions for a number of industries including: ATE, Avionics, SATCOM, Space, and more since it’s founding in 1945. Contact Dow-Key directly for additional RF specs on the MP-Series. The Dow-Key website also has a support center online that is home to a number of helpful white paper product tutorials for customer use.

April 16, 2012 at 5:22 pm | Posted in Uncategorized | Leave a commentRF and Microwave Technology Manufacturer Looks to Inspire and Educate with Release of Downloadable, Next Generation RF Matrix Platform Brochure
Following the release of their next generation RF matrix platform, Dow Key Microwave Corporation is excited for the release of their brand new supplemental brochure to educate users.
The brochure, which is available to download now through the Dow Key Microwave website, will cover next generation RF Matrix software features including additional SCPI commands (fully backward compatible to previous models), Ethernet, USB and HTTP control interfaces. The RF matrix platform itself is discussed in the brochure as well, adding that it is more modular, more compact, field upgradeable, easier to repair, cost effective and offers a faster switching speed altogether. Dow Key is also planning to make their GPIB control interface available to users later this year.
Dow Key Microwave’s MS – Series, or Multiple Switch Series, is just one series included in the brochure that Dow Key is presenting. The MS-Series is populated with individual switches and is aimed at making the control of multiple coaxial switches through software simple for users. The MS-Series has a number of other features that Dow Key wishes to highlight, including the local and remote control options, more switch options (terminated, non-terminated, 18GHz, 26 GHz and 40GHz, normally open and latching switches), functionality with ATE applications and less complex signal routing applications, and more. The MS-Series also allows users to select same or different types of RF switches to put either on the rear panel or inside a box.
With this information and more included in the brand new brochure, Dow Key Microwave explains to users the full capability of their next generation RF matrix platform.
Dow Key Microwave encourages users to visit them at the upcoming NAB Show, held at Las Vegas Convention Center, between April 16th and April 19th as they showcase their new next generation RF matrix platform and their coaxial switches. They will be located in booth SU9607.
Dow Key Microwave Corporation is based in the Southern California coastal city of Ventura and has been providing the technology industry with precision made RF and Microwave switching solutions since it was founded in 1945.
