Product Overview

Mini-Circuits’ RCM-2SP8T-12 comprises a pair of independently controlled, electro-mechanical SP8T switches. Each switch
operates over a wide bandwidth, from DC to 12 GHz, with high isolation and low insertion loss. The absorptive switches are of
a failsafe and break-before-make-configuration, with a minimum lifetime of 5 million switching cycles per switch position, when
used within the noted specifications.

The switch box is constructed in a compact, rugged metal case (8.25 x 8.25 x 4.25”) with 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 Advantages

Dual Mechanical SP8T switches

Operation from DC to 12 GHz

Break-before-make configuration

USB & Ethernet control

Full software support

Mechanical absorptive switches provide high reliability, repeatable high performance and internal
terminations of input signals on the disconnected paths

Supports a wide range of RF test and signal routing applications, including 2G, 3G, 4G, C / S / X
bands 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
