Additional Details

The SMS3923-999 operates over a broad frequency range, typically within the 0.5 to 6 GHz range, but specific details should be verified on the datasheet. It handles pulsed power levels up to a certain peak power, often in the range of several hundred watts to a kilowatt, depending on pulse width and duty cycle. The limiting threshold is precisely set to protect downstream components without significantly degrading receiver sensitivity under normal operating conditions. This limiter module typically has a very fast response time, on the order of nanoseconds, enabling rapid protection against fast transient events. The exact specifications, including frequency range, insertion loss, isolation, return loss, and power handling capabilities, should be verified by consulting the official Skyworks datasheet for this part number.
