Product details
Overview
ATN3580-30 from Skyworks Solutions is a fixed thin-film silicon attenuator chip delivering 30 dB nominal attenuation with ±1.60 dB DC tolerance, ±0.5 dB flatness from 0.1–7 GHz, and minimum 15 dB return loss up to 40 GHz. It uses a balanced TEE resistive structure, handles 1 W CW incident power, and operates from –55 °C to +150 °C in RF signal conditioning paths for test instrumentation and microwave transceivers.
For engineers reviewing the ATN3580-30 datasheet, ATN3580-30 pinout, ATN3580-30 application, or ATN3580-30 equivalent, key selection criteria include broadband flatness stability, high-power handling at elevated temperature, RoHS-compliant rugged die construction, and compatibility with standard ribbon-bond or flip-chip mounting per 518-060 outline.
Technical Context
The ATN3580-30 implements a balanced TEE topology using precision thin-film resistors on high-resistivity silicon, enabling stable 30 dB attenuation across DC–40 GHz. Its design achieves ≥15 dB return loss up to 40 GHz and maintains ±2.0 dB flatness over the full 0.1–40 GHz band.
It is rated for 1 W CW incident power at 25 °C with absolute maximum operating temperature of +150 °C and storage range from –65 °C to +150 °C. ESD robustness includes 1000 V CDM, 2000 V HBM, and 200 V MM ratings.

Equivalent & Alternatives
The following parts are listed as comparable options for similar fixed attenuator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Mini-Circuits VAT-30W2+ | Surface-mount ceramic package; 30 dB ±0.5 dB (0.1–26.5 GHz); 2 W power rating; larger 0.125 × 0.062 inch footprint | Designed for PCB-level integration with solder reflow; less suited for hybrid microcircuit or ribbon-bond assemblies | Select when board space allows larger footprint and higher power margin is required beyond 1 W |
| Qorvo QPA1003 | Active GaAs MMIC attenuator; 30 dB programmable via analog voltage; 0.1–40 GHz; 0.5 W max; requires bias and control lines | Used where variable attenuation or remote control is needed; adds complexity versus passive solution | Select only if dynamic adjustment capability justifies added design overhead and power supply requirements |
Compared with VAT-30W2+ and QPA1003, the ATN3580-30 offers superior broadband flatness stability in hybrid assemblies, eliminates bias/control circuitry, and fits compact 518-060 land patterns-making it optimal for high-density RF modules where simplicity, size, and temperature resilience are critical.

FAQ
What is the DC attenuation tolerance for ATN3580-30?
The ATN3580-30 has a nominal attenuation of 30 dB with a DC tolerance of ±1.60 dB, as specified in Table 2 of the Skyworks datasheet. This tolerance applies at DC and forms the baseline for all frequency-dependent flatness specifications. The ATN3580-30 maintains this precision across its operating temperature range without drift compensation circuitry.
Does ATN3580-30 require DC bias or control signals?
No, the ATN3580-30 is a fully passive thin-film attenuator chip with no active circuitry, bias inputs, or control interfaces. It functions solely as a two-terminal RF component and requires no power supply, ground reference, or digital/analog control lines. The ATN3580-30 operates identically whether DC-coupled or AC-coupled in the signal path.
What is the recommended mounting method for ATN3580-30?
Skyworks specifies ribbon bonding or flip-chip attachment for the ATN3580-30 per Figures 4 and 5 in the datasheet, aligned with the 518-060 outline. Die mounting should follow the suggested land pattern in Figure 7, using conductive epoxy or eutectic solder compatible with gold metallization. Wire bonding is not recommended due to mechanical stress on the thin-film structure.
Can ATN3580-30 be used above 40 GHz?
No-performance is only guaranteed up to 40 GHz per datasheet specifications. While some insertion loss and return loss data may extend beyond 40 GHz in typical curves, Skyworks does not characterize or warrant operation above 40 GHz for the ATN3580-30. For >40 GHz applications, alternative solutions such as waveguide or MMIC-based attenuators should be evaluated.
Is ATN3580-30 compliant with RoHS and lead-free requirements?
Yes, the ATN3580-30 is lead (Pb)-free, RoHS-compliant, and certified as Skyworks Green™ per the Skyworks Certificate of Conformance. Its metallization and substrate materials meet EU Directive 2011/65/EU and subsequent amendments, with full traceability documentation available upon request for the ATN3580-30.
