DATA SHEET ATN3580 Series: Fixed Attenuator Pads Applications Attenuators Features Specified flat response to 40 GHz Return loss > 16 dB to 40 GHz Available at 1–10, 12, 15, 20, 30 and 40 dB Power handling to 1 W CW Rugged thin-film silicon chips Lead (Pb)-free, RoHS-compliant, and Green™ Description The ATN3580 series of attenuator chips incorporates thin-film resistors on high-resistivity silicon to achieve precision attenuation, tight flatness and excellent return loss to 40 GHz. The design uses a balanced TEE resistive structure to assure broad bandwidth performance. The thin-film technology offers improved power-handling capability in comparison to the traditional thickfilm printed attenuator. All ATN3580 attenuator chips are specified for their attenuation at DC. A wafer probe sample test is performed to 40 GHz to assure the flatness specification. The absolute maximum ratings are shown in Table 1. Electrical specifications and minimum return loss are provided in Tables 2 and 3, respectively. Typical performance characteristics are shown in Figures 1 and 2. Drawings for suggested die mount and ribbon attachment, product outlines, and a suggested land pattern are shown in Figures 3 through 7. Skyworks Green™ products are compliant with all applicable legislation and are halogen-free. For additional information, refer to Skyworks Definition of Green™, document number SQ04-0074. Table 1. Absolute Maximum Ratings Characteristic Value Incident power @ 25 °C 1W Operating temperature –55 °C to +150 °C Storage temperature –65 °C to +150 °C Electrostatic discharge: Charged-Device Model (CDM), Class 4 Human Body Model (HBM), Class 2 Machine Model (MM), Class B 1000 V 2000 V 200 V Note: Exposure to maximum rating conditions for extended periods may reduce device reliability. There is no damage to device with only one parameter set at the limit and all other parameters set at or below their nominal value. Exceeding any of the limits listed here may result in permanent damage to the device. CAUTION: Although this device is designed to be as robust as possible, Electrostatic Discharge (ESD) can damage this device. This device must be protected at all times from ESD. Static charges may easily produce potentials of several kilovolts on the human body or equipment, which can discharge without detection. Industry-standard ESD precautions should be used at all times.
