SF2304B - 12/19/12 notes: 1. unless noted otherwise, all specifications apply over the operating temperature range with filter soldered to the specified dem onstration board with impedance matching to 50 ?? and measured with 50 ?? 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 poin t 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. "lrip" or "l" after the part number indicates "low rate initial production" and "eng" or "e" indicates "engineering prototype s." 5. the design, manufacturing process, and specific ations of this filter are subject to change. 6. tape and reel standard ansi / eia 481. 7. either port 1 or port 2 may be used for either input or output in the design. however, impeda nces 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. 8. us and international patents may apply. 9. electrostatic sensitive device. observe precautions for handling. electrical charac teristics, 25 c characteristic sym notes min typ max units center frequency f c 1 175 mhz minimum insertion loss il min 1, 2 7.5 10 db amplitude ripple, f c 0.45 mhz 0.7 1.0 db p-p group delay ripple, f c 0.45 mhz 200 300 ns p-p absolute delay 0.68 1.50 s 1 db bandwidth bw 1 0.90 1.04 mhz 2.5 db bandwidth bw 2.5 1.20 1.38 3 db bandwidth bw 3 1.30 1.46 5 db bandwidth bw 5 1.55 1.66 1.85 30 db bandwidth bw 30 3.21 3.65 40 db bandwidth bw 40 3.47 3.95 ultimate rejection, 186 to 900 mhz 47 50 db input/output return loss, f c 0.45 mhz 10 12 db smp-03 ? high performance 175 mhz saw filter ? hermetic 5 x 7 mm surface-mount case ? single-ended or differential input operation ? complies with directive 2002/95/ec (rohs) absolute maximum ratings rating value units maximum incident power in passband +10 dbm dc voltage on any non-ground terminal 10 vdc operating temperature range -40 to +85 c storage temperature range in tape and reel -40 to +85 c suitable for lead-free soldering - maximum soldering profile 260 c for 30 s 175 mhz saw filter SF2304B single-ended terminating source impedance z s = 50 ohms differential terminating source impedance z s = 100 ohms terminating load impedance z l = 50 ohms case style 6 smp-03 7 x 5 mm nominal footprint lid symbolization, yy = year, ww = week rfm/SF2304B/yyww connection terminals single-ended input port 10 balanced input port 10, 1 single-ended output port 5 ground all others pb preliminary electrical connection
