Attenuators Procurement Notes

Verify the specific ordering suffix matches the required attenuation value, as the ATN3590 family includes variants with different dB ratings. Confirm package type availability, as distribution channels may list die or box packaging options. Ensure the requested quantity aligns with factory pack sizes if applicable. Cross-reference the manufacturer part number with official Skyworks documentation to confirm current production status and lead time requirements before finalizing procurement orders.

Attenuators Selection Notes

Select this component when a fixed 3 dB attenuation is required across a broad DC to 40 GHz spectrum. Consider the 2W power handling capability for high-power RF environments. Evaluate the -55°C to +150°C temperature range against environmental conditions. Compare return loss specifications at target frequencies to ensure signal integrity meets system requirements. Verify impedance matching for 50 Ohm systems.

Attenuators Part Context

The ATN3590 series consists of fixed resistive attenuators manufactured by Skyworks Solutions Inc. These devices are part of a broader family offering various attenuation values, including 1 dB and 7 dB variants. The series is characterized by its use of thin film technology and through-die via construction, providing consistent performance in demanding RF applications. The ATN3590-03 specifically denotes the 3 dB attenuation variant within this product line.

Attenuators Replacement Considerations

Direct substitutes within the same family include ATN3590-01 (1 dB) and ATN3590-07 (7 dB), though attenuation values differ. No other direct equivalent part numbers are confirmed in public documentation. Verify functional compatibility regarding impedance and power ratings when considering alternative manufacturers.
