Pasternack is a leading manufacturer and supplier of RF, microwave and millimeter wave products. Able to withstand extreme conditions, on earth or in space, several key industries around the world continue to rely on our products, including avionics, military electronics, IFF, SATCOM, ECM, industrial/manufacturing and oil/gas.

When a signal needs to be reduced to protect measurement equipment or other circuitry, an RF attenuator will do the job seamlessly. It extends the range of power meters and amplifiers while impedance matching circuits by reducing the VSWR seen in adjacent components.

We carry a wide selection of high power RF attenuators across several attenuation levels, frequency ranges and power dissipation ranges. Also known as RF pads, our radio frequency microwave attenuators, like the PE7424-03 model, lower the amplitude of a signal (attenuate) to a known amount. Our high load attenuators are available with attenuation levels between 3 dB and 40 dB. They can support frequency ranges from DC up to 18 GHz and have a flat radio frequency response and performance.

Pasternack's high wattage RF attenuators, such as the PE7424-30, have a power rating of 10 Watts, 25 Watts, 50 Watts or 100 Watts. They also have a peak power rating of 500 Watts, with a power handling capability of up to 100W (CW). The 10 Watt and 25-Watt models feature bi-directional operation, while the 50 Watt and 100-Watt versions support directional operation.

Our N-type attenuators, including the PE7426-10 model, are constructed with black anodized aluminum heatsink bodies and are designed with large cooling fins that allow for heat dissipation at high temperatures. All our coaxial attenuators feature in-series gender interfaces and are available in male-female configurations with SMA and Type-N high-power connector options. All models are also Export Administration Regulations (EAR99) compliant.

Our complete line-up of high power attenuators, featuring models like the PE7428-15 and PE7428-20, can prevent signal overload in amplifiers, receivers and detectors by continuously adjusting the signal level to an optimal range. This is why they are ideally suited for power limiting in production and R&D applications, impedance matching and signal leveling inside RF test systems.

Our large in-stock inventory of high-performance, high-frequency RF attenuators are housed at our ultramodern ISO 9001:2008 certified production facilities in Lewisville, Texas USA. Recognized for our unmatched quality, quick turnaround, great customer service, and technical support, all our RF, microwave and millimeter-wave products are competitively priced, available for same-day shipping worldwide, with no minimum purchase requirement.
