SA3N5W-10 is a 10 dB fixed attenuator designed for RF/microwave applications, featuring N male (plug) to N female (jack) connectors and an aluminum body. The device operates bidirectionally across a frequency range from DC to 3 GHz with a nominal attenuation of 10±0.75 dB and maintains a VSWR of less than 1.2:1. It is rated for a maximum continuous wave (CW) input power of 5 watts, with peak power handling of 500 watts (5 µs pulse, 0.5% duty cycle), and operates reliably over a temperature range of -55°C to +125°C. The attenuator is commonly used in instrumentation, precision measurements, prototyping, and production systems to reduce signal levels, protect measurement equipment, extend the range of power meters and amplifiers, and prevent signal overload in receivers and detectors.
