4-Stage I2C-Controlled Attenuator Module for the RF Cogs™ Modular Series

The RFC-AT60 is a programmable attenuator module for use with high frequency RF signals. The attenuator consists of four cascaded 15 dB attenuator sections which can be electronically switched in or out. The attenuation is set via signals sent to the module over an I2C bus. Each module is individually addressable and can be used alone or with additional attenuator modules. It can also be used with other modules in this family which provide different functions like switching or amplification.

Because this device employs electronic switching, there are no mechanical parts to wear out or contacts that can become tarnished.

The I2C signals and DC power connections are made through a multi-pin connector. There is a second connector port wired in parallel with the first which allows all of the modules to be daisy-chained together from one module to the next.

The RF connectors used on the RFC-AT60 switch module are F-type connectors, widely used in CATV and video applications.

The modules in this series can be mounted flat to a base plate or vertically into an optional 3U sub-rack (standard 19 in. rack) along with the controller and other modules.
