ATC AT Series 0603 RF/Microwave Attenuator EIA 0603 SMT Thin Film Design Highest Power in Class Power Rating Up to 1 watt AlN construction Frequency Response +/- 0.5 dB Balanced Pi design Characterized to 20 GHz Non-Magnetic CPW and Microstrip RoHs compliant Applications ATCs new RF/ Microwave SMT Attenuator Series (AT) is manufactured with the highest quality materials for reliable ENVIRONMENTAL SPECIFICATIONS and repeatable performance. These devices are constructed OPERATING TEMPERATURE: -55C to +150C with Aluminum Nitride (AlN) and are available in a standard 100% inspection Per MIL-STD-883 EIA 0603 case size. The AT Series exhibits excellent performance characteristics for the most demanding RF/ Microwave applications. ELECTRICAL AND MECHANICAL The AT provides virtually flat loss over a broad frequency SPECIFICATIONS spectrum. Thin film metallization provides for very stable characteristics over temperature and time. Its balanced NOMINAL IMPEDANCE: 50 Ohms PI design provides even current distribution and accurate FREQUENCY RANGE: DC to 20 GHz attenuation characteristics from DC to 20 GHz. It is designed to meet a wide range of RF and microwave large and small VALUES AVAILABLE: 0 to 10 dB (1 dB increments) signal level applications. The AT is ideal for impedance INPUT POWER CW: matching, input padding, signal level tuning, and many 1W: 0 to 6 dB other critical RF/ Microwave applications. The AT is rated 0.75W: 7 to 10 dB highest power in class and is suitable for microstrip and CPW VSWR: 1.25:1 typical applications. The non-magnetic termination is available providing a range of FREQUENCY RESPONSE (dB): attachment options such as eutectic die-bonding, conductive D.C. to 10 GHz: 0.50 dB epoxies, and soldering. The AT is fully compatible with high >10 GHz: 1 dB speed automated pick-and-place processing. SUBSTRATE MATERIALS: AlN (1 to 10 dB) Typical applications: Telecommunications, Satellite Communi- Al O (0 dB) 2 3 cations, Cellular Base Stations, Microwave Radio, ISM, RESISTORS: Tantalum Nitride RF/Microwave Power, Military /Aerospace, Test and Measurement. TERMINAL: Thin Film metal stack, Au Functional applications: Impedance Matching, Input Padding, Signal Level Tuning, Signal Conditioning.
