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.”

Dowkey at the Autotestcon Show
October 21, 2010 at 7:22 pm | Posted in Ceramic & Microwave Products, Coaxial Switches, Dow-Key, RF matrices, Switch Matrices | Leave a commentOrlando, Florida (September 13-16, 2010) – Last month, Dow-Key Microwave participated in the Autotestcon Show, held in Orlando, Florida, from September 13th through 16th. The theme of this year’s conference reflected upon not only the fact that 2010 is Autotestcon’s forty-fifth year, but also that their technical program focuses on the future of automatic test. Dow-Key Microwave joined over 100 other exhibiting organizations and United States Military divisions in providing over 250 exhibition booths.  By participating in this show, Dow-Key Microwave’s attendees, Adolf Cheung, Larry Neeley, Greg Marinez and Sara Nazemzadeh, were able to meet senior military and aerospace leaders, as well as intermingle with other professionals in the industry, including weapon systems managers, acquisition officials, engineers and logisticians.Dow-Key Microwave held its exhibition at booth number 836, which turned out to be a great location since it was in a high traffic area. Dow-Key’s products on display included the solid state 3202 matrix, the electromechanical 4104 matrix, the fiber optics matrix, PXI modules, and many coaxial and waveguide switches that are great for test setups, as well as ATE applications. The fiber optics matrix, which is one of the latest additions to Dow-Key’s product line, really captured a high level of interest. Participation in the show also provided a great opportunity to reveal the company’s new Space Brochure for the first time. During the three day exhibition, Dow-Key Microwave also took part in the “Tech Trek” competition which was sponsored by Evaluation Engineering. In this competition, visitors of Dow-Key’s booth had the chance to win an iPod, iPad, or various other electronics through multiple daily drawings. This competition was a fun event that gave Dow-Key Microwave the opportunity to meet and interact with may great engineers and leaders within the RF industry. The outcome of the show was truly great, because it was very well attended, and Dow-Key was able to capture many high quality leads. Due to this great turn out, Dow-Key Microwave plans to participate in the next Autotestcon show, which will be held next year in Baltimore. |

Dow-Key Notes From IEEE MTT-S International Microwave Symposium 2010
June 4, 2010 at 3:37 pm | Posted in Ceramic & Microwave Products, Coaxial Switches, Waveguide Switches | Leave a commentTags: Ceramic & Microwave Products, Ieee Mtt-S International Microwave Symposium, Microwave Symposium 2010
The MTT-S International Microwave Symposium was held in Anaheim, California, during May 23-28.
It is an IEEE sponsored show annually held at different locations across US and allows a premier international conference for technologists involved in all aspects of microwave theory and practice to meet. The show heavily focuses on RF switch technology (and among many other RF applications) and is our most important trade show every year.
Together with our sister companies in Ceramic & Microwave Products (CMP), we have attended this show over several years and this year, as it was on our home base (80 miles south from our factory in Ventura, California), many of Dow-Key’s Sales and Engineering team members were able to attend the conference sessions and walked the show, in addition to networking with other companies.
We had a very successful week, where we met with many of our customers and conducted business on the spot. As the show is well attended with our representatives across US and internationally, we networked with many of them and other familiar faces within the RF & Microwave industries. This show provides a great atmosphere, for not only us but for everyone, to do business and mingle with similar minded people. And the results are always rewarding.
We presented many of our hot item products such as our commercial coaxial switches and lightweight waveguide switches to be used for testing applications, antenna signal switching, or for many other signal routing applications. We also displayed our ruggedized switches (SPDT, Transfer, and Waveguide) for space and military application where switches need to operate in severe environment. Furthermore, we show cased our SPDT miniature pin mount switch that goes up to 3 GHz and can be soldered to a PCB for RF switching applications.
Among our extensive matrix portfolio, we presented our larger matrix system that allows multiple inputs to be switched to multiple outputs – our popular solid state L-band 12×12 matrix. And our smallest and very popular 1 RU matrix populated with same or different switches (4104 model) was also show cased. In addition, we brought our PXI module solution that is for testing multiple RF signals at ease to the show. All these solutions can be found in our new product catalog and downloaded from our website.
The 2011 IEEE MTT-S International Microwave Symposium will be held in Baltimore, Maryland, in June and record high attendance is expected. We will be there together with our CMP group – once again with booths side-by-side to present a broad range of RF & Microwave products to current and prospect customers. We look forward to seeing you in Baltimore.
How To Create Your Own Switching System Using Dow-Key Products

VENTURA, Calif. (August 15, 2008) – Dow-Key Microwave is pleased to release three new Application Notes describing how one can build their own switching system by using Dow-Key CANBus switches together with an ENET or a GPIB Kit. The difference between the ENET and the GPIB kit lies in that the translator board uses either the TCP/IP protocol or the GPIB protocol respectively to transmit data.
