Product details
Overview
ATN3580-10 from Skyworks Solutions is a fixed thin-film silicon attenuator chip with nominal 10 dB attenuation, ±0.35 dB DC tolerance, ±0.2 dB flatness up to 12 GHz, and minimum 15 dB return loss to 40 GHz. It uses a balanced TEE resistive structure for broadband RF signal conditioning in microwave test equipment and high-frequency transceiver front-ends.
For engineers reviewing the ATN3580-10 datasheet, ATN3580-10 pinout, ATN3580-10 application, or ATN3580-10 equivalent, key selection criteria include its 1 W CW power handling, -55 °C to +150 °C operating temperature range, RoHS-compliant lead-free construction, and guaranteed flatness performance across 0.1–40 GHz.
Technical Context
The ATN3580-10 implements a balanced TEE topology on high-resistivity silicon substrate, enabling broadband impedance matching and stable attenuation over 0.1–40 GHz. Its thin-film resistor fabrication ensures tighter tolerance control and higher thermal stability than thick-film alternatives.
Electrical behavior is characterized at 25 °C with DC-coupled operation; attenuation flatness degrades predictably beyond 12 GHz (±0.30 dB to 26.5 GHz, ±0.50 dB to 40 GHz), while return loss remains ≥15 dB across full bandwidth per Table 3.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Nominal attenuation | 10 dB - precise signal level reduction without amplification or active control |
| DC tolerance | ±0.35 dB - maximum deviation at DC, defining baseline calibration accuracy |
| Attenuation flatness (0.1–12 GHz) | ±0.2 dB - ensures consistent signal suppression across L/S/C bands |
| Minimum return loss (0.1–40 GHz) | 15 dB - limits VSWR to ≤1.43, reducing mismatch-induced ripple and reflections |
| Power handling | 1 W CW - supports continuous high-power RF testing without thermal derating |
| Operating temperature | -55 °C to +150 °C - enables deployment in aerospace, defense, and under-hood automotive RF modules |
| Package outline | 518-060 - 0.060 × 0.060 inch ceramic chip with defined die-mount land pattern |
Pinout & Package
ATN3580-10 is a two-terminal passive chip device with no polarity or directional pin assignment. It is mounted as a surface-mount die using ribbon bonding or conductive epoxy on a 518-060 outline footprint (0.060″ × 0.060″). No discrete pins exist - RF signal path flows between opposing metallized edges.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Terminal 1 | RF input / source side | Primary signal entry point; symmetric with Terminal 2 for bidirectional operation |
| Terminal 2 | RF output / load side | Signal exit point after fixed 10 dB loss; identical electrical role to Terminal 1 |

Equivalent & Alternatives
The following parts are listed as comparable options for similar fixed-attenuation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Mini-Circuits VAT-10W+ | Surface-mount ceramic package; 10 dB ±0.4 dB tolerance; 0.01–20 GHz bandwidth; 2 W power rating | Limited to 20 GHz - unsuitable for Ka-band or 40 GHz test systems | Select when higher power margin is required below 20 GHz and wider flatness tolerance is acceptable |
| Qorvo QPA1009 | Monolithic GaAs MMIC attenuator; 10 dB ±0.5 dB; 0.1–40 GHz; integrated bias circuitry; 0.5 W rating | Active bias requirement adds design complexity; lower power handling than ATN3580-10 | Select only if DC blocking or integrated control interface is needed - otherwise ATN3580-10 offers superior simplicity and reliability |
Compared with VAT-10W+ and QPA1009, the ATN3580-10 delivers wider bandwidth (to 40 GHz), tighter flatness (±0.2 dB to 12 GHz), and higher CW power handling (1 W) in a passive, DC-coupled, zero-bias solution ideal for high-frequency instrumentation and defense RF subsystems.

FAQ
What is the DC attenuation tolerance of the ATN3580-10?
The ATN3580-10 has a DC attenuation tolerance of ±0.35 dB as specified in Table 2 of the Skyworks datasheet. This tolerance defines the maximum allowable deviation from the nominal 10 dB value at DC and forms the baseline for all frequency-dependent flatness specifications. The ATN3580-10 maintains this tight tolerance across its full operating temperature range of -55 °C to +150 °C.
Does the ATN3580-10 require DC blocking capacitors?
No, the ATN3580-10 is a DC-coupled passive attenuator and does not require DC blocking capacitors. Its balanced TEE structure operates from DC to 40 GHz, making it suitable for applications involving baseband signals, pulse modulation, or low-frequency RF where DC continuity is essential. The ATN3580-10 is explicitly specified for attenuation at DC per the Skyworks datasheet description.
What is the recommended mounting method for the ATN3580-10?
Skyworks recommends die mounting the ATN3580-10 using conductive epoxy or eutectic solder onto a 518-060 land pattern, followed by ribbon bonding to both terminals. Figure 4 of the datasheet provides the suggested die mount and ribbon attachment drawing for ≥6 dB attenuators like the ATN3580-10. Mechanical clamping or flip-chip bonding is not supported. The ATN3580-10 must be handled per ESD Class 2 (HBM) precautions.
Is the ATN3580-10 suitable for space-level applications?
The ATN3580-10 is not certified for space-level use, though its -55 °C to +150 °C operating temperature range and rugged thin-film silicon construction support demanding terrestrial and airborne environments. It lacks radiation hardness qualification, MIL-PRF-19500 screening, or QML-V certification. For space applications, users must perform independent radiation testing and lot acceptance per their program requirements. The ATN3580-10 itself is rated for commercial and industrial use only.
How does the ATN3580-10 compare to thick-film attenuators in power handling?
The ATN3580-10 achieves 1 W CW power handling due to its thin-film silicon construction, which provides superior thermal conductivity and resistor stability compared to traditional thick-film printed attenuators. Thick-film variants typically max out at 0.25–0.5 W before significant drift or failure occurs. This 2×–4× improvement enables the ATN3580-10 to sustain continuous operation in high-power test fixtures and radar transmitter stages where the ATN3580-10's thermal performance is critical.
