Dow-Key Microwave’s new Reliant SwitchTM is a 1x6 bidirectional coaxial switch with an operating frequency from DC to 26. 5 GHz, which covers the typical 6 GHz test range and beyond for high-speed testing. This switch is designed with a high isolation of 100 dB (up to 4 GHz) to maintain RF consistency between port-to-port testing. Moreover, the switch can sustain a guaranteed insertion loss repeatability of 0.03 dB across the entire frequency band. This coaxial switch has an extended life cycle where each position can switch a minimum of 5-Million cycles - a 5X improvement from a typical multi-position switch.
This waveguide switch is available with both a manual and electrical drive type and with an E or H waveguide structure. Twelve different models are available, all with varying frequency ranges, switching times, loss, isolation, and average power. The line collectively covers the 2.6 to 40 GHz frequency range.

The MAS4488 is a broadband matrix switch with an 8 input, 8 output, non-blocking configuration. The system itself is comprised of a processor board, an 8x8 matrix, a LAN interface, a redundant power supply, and manual control.
This SPDT switch covers the 4.9 to 5.9 GHz frequency range and features a low noise figure of 2.5 dB, 12 dB gain, and high transmit-to-receive isolation (ideal for high power applications).
Switch matrices are typically used in the design verification or manufacturing phase of test systems. They’re designed to move signal routing and signal conditioning to a test system’s central location. This makes the characterization of the calibration plane between the DUT and the test equipment simpler, reduces insertion loss, improves signal integrity, and better controls phase issues. They can be used in both commercial wireless and aerospace/defense settings. This page provides an overview of Dow-Key Microwave’s offerings as it relates to switch matrices.
This line of SPST and SPDT PIN diode switches feature high power handling, low insertion loss, high antenna-to-receive-isolation, a broad frequency range (20 MHz to 6 GHz), and much more. There are currently nine different SPST and SPDT models available in this series, all with varying maximum power, package sizes, operating frequency ranges, and more.
This single pole, 36 throw (SP36T) switch features multi-octave frequency range coverage, 70 dB min isolation, 1 W CW power handling, 7 dB max insertion loss, a single +5 V supply, 100 nsec switching speed, and low profile packaging.
RLC Electronics’ waveguide switches are available in SPDT and transfer configurations, can be manually or remotely controlled, and offer a choice of coil voltages and optional indicator contacts.
