Abstract :
This letter describes the design and implementation of a wideband radio frequency-baseband multiplexer. This device makes it possible to superimpose radio frequency noise to a functional baseband signal with controlled and repeatable transfer characteristics. The baseband path has a measured dc-380 MHz bandwidth, while the radio frequency path (up to 1 W) has a 150 kHz-5 GHz bandwidth. This multiplexer can be used for electromagnetic conducted immunity testing of digital and mixed-signal devices.
