- Precision IF SAW Filter Excellent Size-to-Performance Ratio Hermetic Surface-mount Case Single-ended Input and Output Complies with Directive 2002/95/EC (RoHS) Absolute Maximum Ratings Rating Value Units Maximum Incident Power in Passband +18 dBm Maximum DC Voltage Between any Two Terminals 30 VDC Storage Temperature Range in Tape and Reel -40 to +85 °C Suitable for Lead-free Soldering - Maximum Soldering Profile 260°C for 30 s
- Unless noted otherwise, all specifications apply over the operating temperature range with filter soldered to the specified d emonstration board with impedance matching to 50 Ω and measured with 50 Ω network analyzer. 2. Unless noted otherwise, all frequency specifications are referenced to the nominal center frequency, fc. 3. Rejection is measured as attenuation below the minimum IL point in the passband. Rejection in final user application is depe ndent on PCB layout and external impedance matching design. See Application Note No. 42 for details. 4. The turnover temperature, T O, is the temperature of maximum (or turnover) frequency, f o. The nominal frequency at any case temperature, Tc, may be calculated from: f=fo[1-FTC(To-Tc)2]. 5. The design, manufacturing process, and specifications of this filter are subject to change. 6. 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. 7. US and international patents may apply. Impedance Matching to 50 Ω Single-ended Source and Load External L-C Case Style SM1154-14, 11.5 x 4 mm Nominal Footprint Lid Symbolization (YY = year, WW = week) SF2221A, YYWW Pb CAUTION: Electrostatic Sensitive Device. Observe precautions for handling. Notes: Preliminary SM1154-14
