SF2038B-3-011207 notes: 1. unless noted otherwise, all specifications apply over the operating temperature range with filter soldered to the specified demo nstration board with impedance matching to 50 w and measured with 50 w 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 depende nt 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 prototypes." 5. the design, manufacturing process, and specifications 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, impedances and impedance matching may va ry 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. rfm, stylized rfm logo, and rf monolithics, inc. are registered trademarks of rf monolithics, inc. 10. ?copyright 1999, rf monolithics inc. 11. electrostatic sensitive device. observe precautions for handling. electrical characteristics characteristic sym notes min typ max units nominal center frequency f c 1 76.500 mhz passband insertion loss il 10.0 12.0 db 1db passband bw 1 1 12.5 14.0 mhz 15db bandwidth bw 15 16.8 18.0 mhz 30db bandwidth bw 30 18.0 19.2 mhz amplitude ripple over fc 6.25 mhz 0.70 1.3 db p-p group delay variation over fc 6.25 mhz gdv 40 150 ns p-p rejection 50 to 64.44 mhz 1, 3 40 46 db 64.44 to 66.70 mhz 36 41 86.30 to 87.54 mhz 30 44 87.54 to 91.50 mhz 31 44 91.50 to 100 mhz 40 47 operating temperature range t a 1 -40 +85 c frequency coeffieient ftc -87 ppm/c differential input 175 ohms differential output 180 ohms case style 6 smp-03-s 7 x 5 mm nominal footprint lid symbolization (yy=year, ww=week, s=shift) see note 4 rfm SF2038B-3 yywws smp-03-s ? designed for sdars if receiver ? low insertion loss ? 5.0 x 7.0 mm surface-mount case ? differential or single ended input and output ? complies with directive 2002/95/ec (rohs) absolute maximum ratings rating value units maximum incident power in passband +10 dbm max. dc voltage between any 2 terminals 30 vdc storage temperature range -40 to +85 c max soldering profile 265c for 10 s 76.500 mhz saw filter SF2038B-3 pb connection port 1 hot port 1 ground return or hot port 2 hot port 2 ground return or hot case ground terminals 10 1 5 6 all others electrical connections
