State of the Art, Inc. 1512 High Frequency Chip Attenuator Thin Film, Wraparound Terminations PERFORMANCE CHARACTERISTICS Attenuation Factor Maximum Power Frequency Range The Frequency response data plotted below shows an example of VSWR obtained in pressure contact fixtures. Data for chips which are solder attached to matched circuit traces may exhibit even better performance. 1 to 20 dB 500 milliwatts DC to 10 GHz 2 1.9 ENVIRONMENTAL PERFORMANCE* 1.8 0.02% 0.02% 0.02% 0.02% 0.03% 0.03% 1.7 1.6 VSWR Thermal Shock Low Temperature Operation Short Time Overload Resistance to Bonding Exposure Moisture Resistance High Temperature Exposure 1.5 1.4 1.3 1.2 * Typical percent resistance change -test methods and actual specification limits are in accordance with Mil-PRF-55342. 1.1 1 0 1 Absolute Percent Resistance Change TYPICAL LIFE PERFORMANCE 2 3 4 5 6 Frequency (GHz) 0.5 Attenuation Tolerance 0.4 0.3 Increment (dB) 0.2 DC - 4 GHz 4 - 8 GHz 8 - 13 GHz 13 - 16 GHz 16 - 20 GHz 1 to 10 dB 0.5 dB 0.5 dB 0.5 dB 0.75 dB 1.0 dB 11 to 20 dB 0.5 dB 0.5 dB 0.75 dB 1.0 dB 1.5 dB 0.1 0.0 0 250 500 1K 2K 4K 6K 8K 10K Test Duration in Hours Consult our Engineering Department for frequency specific performance requirements. PART NUMBERING S 1512 C C 10B0 B (******) B PACKAGING CODE: - TR = Tape/Reel - W = Waffle Carrier (Default packaging is Bulk) SCD REFERENCE TERMINATION FINISH: B: Sn60 over nickel barrier, Y: Silver over nickel barrier VALUE CODE: Three or Four digits are used to express the attenuation value (available from 1 to 20 dB in 1dB increments). The letter "B" is used to represent the decimal. Example: 10B0 = 10 dB, 1B5= 1.5 dB, etc. PRODUCT DESIGNATION: C: Attenuator on alumina TERMINATION TYPE: C: Wraparound terminations SIZE CODE GRADE: S: Standard Production H: High Reliability (For screening options, contact the factory) MECHANICAL INCHES Length Width Thickness I/O Length (a) I/O Width (b) I/O Gap (c) Ground (d) I/O Ground Gap (e) Approx.
