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, the Leader in RF/Microwave Switch Manufacturing, Has Released A New White Paper on Switch Solutions for the Public
Ventura, CA (PRWEB) August 23, 2011
Dow-Key Microwave Corporation, the leading manufacturer of electromechanical switches for radio frequency (RF) and microwave applications is proud to announce the release of their brand new white paper, “Switch Solutions for Systems with Low PIM Requirements.”
The “Switch Solutions for Systems with Low PIM Requirements” addition to the white paper page explains that the effect of nonlinearities is becoming more prominent in signals with higher amplitude, which causes intermodulation signals to interfere with the desired system behavior and introduces unwanted results. In order to avoid this and reduce intermodulation in passive devices, low PIM designs are necessary.
Dow-Key Microwave Corporation has invested in R&D for new RF switch products and was excited to introduce to the market a family of special RF switches which meet the very stringent and low intermodulation requirements imposed by today’s test and communication industries. The launch of the “Low PIM family” has provided capability for a much improved PIM performance (below-160 dBc) and is available as an option to users with low PIM needs.
The new white paper focuses on defining Passive Intermodulation, and the concerns around PIM. It also discussed the cause of PIM in both general terms and in switches while also providing a solution for systems with low PIM requirements. For more information regarding this or other Dow-Key Microwave white papers, contact Dow-Key Technical Staff.

Dow-Key Offers Low PIM Switches

VENTURA, Calif. (November 18, 2008) – Dow-Key Microwave offers a new option to their coaxial switch families – the Low PIM option.
Passive Intermodulation (PIM) is referred to distorted signals that occur when two or more signals in passive components contribute to non-linear response. PIM is a concern in particular when two or more transmitted signals share a common antenna or multiple base station transceivers are at the same site.
To avoid high intermodulations levels, Dow-Key, now offers the “W” option that is designed to allow low PIM levels. The average PIM level for a multiposition RF switch is -160 dBc with a 3rd order IM at -125 dBm.
