Product Overview
Mini-Circuits' RC-3MTS-26 comprises of three independently controlled, electro-mechanical transfer switches. Each switch operates over a wide bandwidth, from DC to 26.5 GHz with high isolation (80 dB typical), low insertion loss (0.3 dB typical) and high input power rating. The switches are of a fail safe and break-before-make-configuration using a patented design which ensures long-term reliability, with a minimum life time of 2 million switching cycles when used within the noted specifications.
The switch box is constructed in a compact, rugged metal case (4.5 x 6.0 x 2.25") with all SMA(f) RF connectors on the front panel.The switches are controlled via USB or Ethernet, allowing control directly from a PC, or remotely over a network. Full software support is provided, including our user-friendly GUI application for Windows and a full API with programming instructions for Windows and Linux environments (both 32-bit and 64-bit systems).

Key Features
Feature
Three transfer switches

Advantages
Transfer switches provide a simple DPDT switch application (2 input to 2 output switch matrix) and are a useful building block in much larger switch matrices

Fail-safe design

The switches revert to a known default state when the DC supply is removed, allowing their use in systems that must continue to operate safely in the event of power failure

Break-before-make configuration

Prevents a momentary connection of the old and new signal paths, reducing the inconsistent transient effects that could otherwise be observed during switching

USB & Ethernet control Full software support

USB HID and Ethernet (HTTP / Telnet) interfaces provide easy compatibility with a wide range of software setups and programming environments
User friendly Windows GUI (graphical user interface) allows manual control straight out of the box, while the comprehensive API (application programming interface) with examples and instructions allows easy automation in most programming environments
