Product Overview

Mini-Circuits’ RC-2SPDT-40 comprises of two independently controlled, electro-mechanical SPDT switches. Each switch
operates over an extremely wide bandwidth, from DC to 40 GHz with high isolation and low insertion loss. The reective switches
are of a failsafe and break-before-make-conguration, with a minimum lifetime of 2 million switching cycles per switch when
used within the noted specications.

The switch box is constructed in a compact, rugged metal case (4.5 x 6.0 x 2.25”) with all 2.92mm (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 Advantages

Two mechanical SPDT switches Mechanical reective switches provide highly reliable and repeatable performance.

Operation from DC to 40 GHz

Break-before-make conguration

USB & Ethernet control

Full software support

Supports a wide range of RF test and signal routing applications, including 2G, 3G, 4G and 5G, with
a single device

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

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
