SF2289C • Low Loss SAW Filter • 5.0 x 5.0 mm Surface-mount Case • Complies with Directive 2002/95/EC (RoHS) 155 MHz SAW Filter Pb Absolute Maximum Ratings Rating Value Units Maximum Incident Power in Passband 0 dBm Maximum DC Voltage on any Non-ground Terminal 10 V -40 to +85 °C Storage Temperature Range in Tape and Reel Maximum Soldering Profile 265 °C for 10 s SM5050-8 Electrical Characteristics Characteristic Center Frequency Insertion Loss, fC ± 4 MHz Rejection Referenced to ILMIN: fC-38.8 to fC- 100 MHz fC+38.8 to fC+100 MHz Operating Temperature Range Input Impedance at fC Output Impedance at fC Case Style Lid Symbolization Sym Notes fC IL 1 1 Typ Max Units 6.5 MHz dB 155 1, 3 TA Min dB 50 42 -10 1 +50 °C 263 Ω || 8.7 pF 685 Ω || 9.1 pF SM5050-8 5 x 5 mm Nominal Footprint A36 6 50 ohm Matching Network 12 pF 12 pF 56 nH 56 nH CAUTION: Electrostatic Sensitive Device. Observe precautions for handling. NOTES: 1. 2. 3. 4. 5. 6. 7. 8. 9. Unless noted otherwise, all specifications apply over the operating temperature range with filter soldered to the specified demonstration board with impedance matching to 50 Ω and measured with 50 Ω network analyzer. Unless noted otherwise, all frequency specifications are referenced to the nominal center frequency, fc. Rejection is measured as attenuation below the minimum IL point in the passband. Rejection in final user application is dependent on PCB layout and external impedance matching design. See Application Note No. 42 for details. "LRIP" or "L" after the part number indicates "low rate initial production" and "ENG" or "E" indicates "engineering prototypes." The design, manufacturing process, and specifications of this filter are subject to change. Tape and Reel Standard ANSI / EIA 481. Either Port 1 or Port 2 may be used for either input or output in the design. However, impedances and impedance matching may vary between Port 1 and Port 2, so that the filter must always be installed in one direction per the circuit design.
