PE7203-20

Overview

The PE7203-20 is a fixed attenuator manufactured by Pasternack Enterprises. It provides a nominal attenuation of 20 dB with a frequency range extending from DC to 6 GHz. The device features a 7/16 DIN male connector on one port and a 7/16 DIN female connector on the other, facilitating directional signal measurement applications. Constructed with a black anodized aluminum heatsink body, it supports a maximum power handling capacity of 100 watts. This configuration ensures reliable performance in high-power RF environments requiring precise signal reduction.

Feature Summary

• Directional design suitable for signal monitoring and measurement
• Robust black anodized aluminum heatsink body for thermal management
• Mixed gender connector interface combining male and female 7/16 DIN ports

Applications

• High-power RF signal attenuation in test and measurement setups
• Signal level adjustment in microwave communication systems up to 6 GHz
• Directional coupler input/output conditioning in radar applications

Procurement Notes

Verify the specific connector gender orientation matches the system requirement, as this model combines male and female 7/16 DIN interfaces. Confirm that the 100-watt power rating aligns with the operational peak power levels of the application. Ensure the frequency specification covers the entire operational bandwidth up to 6 GHz without significant deviation. Check for any specific mounting requirements associated with the heatsink body design.

Selection Notes

Select this component when a fixed 20 dB reduction is required within the DC to 6 GHz spectrum. The mixed-gender 7/16 DIN interface simplifies cabling in systems where standard gender matching is not available. The high power handling capability makes it suitable for transmitter output stages or high-power receiver inputs. Consider the physical dimensions and weight if space constraints are critical in the installation environment.

Part Context

This part belongs to Pasternack's line of fixed attenuators designed for microwave frequencies. The 7/16 DIN connector type is commonly used in base station and industrial RF applications due to its robust mechanical connection and high power handling capabilities compared to smaller connectors like SMA or N-type. The directional nature distinguishes it from standard bidirectional attenuators.
