Low PIM coaxial switches with N-Type connectors from Dow-Key Microwave December 4, 2012

Dow-Key Microwave continues to be the leader in providing wireless and RF test industries with the lowest PIM ratings of coaxial switches and is exited to announce the next series of Low PIM switches now available with N-type connectors (in addition to SMA connectors).

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.

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.

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, which 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.

The main applications for new switches are wireless radio systems and test equipment.
