PE7020-20

Overview

The Pasternack PE7020-20 is a fixed RF attenuator designed for high-power applications. It provides a nominal attenuation of 20 dB with SMA male to SMA female connectors. The device operates within a frequency range up to 18 GHz and features a black anodized aluminum heatsink body. It is rated for a maximum input power of 50 Watts at the stated attenuation value. The unit maintains a characteristic impedance of 50 Ohms, ensuring compatibility with standard RF systems requiring precise signal reduction in demanding environments.

Feature Summary

• High power handling capability rated at 50 Watts
• Broadband operation extending up to 18 GHz
• Durable black anodized aluminum heatsink construction

Applications

• RF test and measurement setups
• Signal conditioning in communication systems
• Power level reduction in microwave circuits

Procurement Notes

Verify that the specific application requires a fixed 20 dB attenuation value rather than variable or step attenuation. Confirm that the system power levels do not exceed the 50 Watt rating at the operating frequency. Ensure SMA connector gender matches the source and load interfaces. Check environmental requirements against the aluminum heatsink material specifications.

Selection Notes

Select this component when high power dissipation is critical compared to standard low-power attenuators. The 18 GHz bandwidth supports wideband microwave applications. Consider the physical size of the heatsink body for enclosure space constraints. Verify that SMA interface types are suitable for the intended cable connections and mating hardware.
