Additional Details

The SMS3926-998LF is engineered to operate across a broad frequency range, often between 0.5 GHz and 6 GHz, but always consult the datasheet for specific frequency coverage. It's capable of handling substantial peak power levels, typically in the hundreds of watts, depending on pulse width and duty cycle, effectively safeguarding downstream components. The limiter threshold is finely tuned to provide protection without significantly degrading receiver sensitivity during normal operation. The module offers a rapid response time, typically in the nanosecond range, enabling swift protection against fast transient events. Refer to the official Skyworks datasheet for detailed specifications, including precise frequency range, insertion loss, isolation, return loss, power handling capabilities, and other important parameters.
