SF1143B-4 - 3/28/08 1. unless noted otherwise, all specifications apply over the operating tem perature range with filter so ldered to the specified d emonstration board with impedance matching to 50 and measured with 50 network analyzer. 2. unless noted otherwise, all frequency specifications ar e 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. "lrip" or "l" after the part number indicates "low rate in itial 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, 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. 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. electrical characteristics characteristic sym notes min typ max units nominal center frequency f c 1 315.000 mhz passband insertion loss at fc il 15.1 17.0 db 1db passband bw 1 1, 2 6.35 7.05 mhz fast amplitude ripple over fc 6.35 mhz 1.5 db p-p group delay variation over fc 6.35 mhz gdv 23 200 ns p-p rejection 100 to fc-10.3 and fc+10.3 to fc+100 mhz 1, 2, 3 38 45 db operating temperature range t a 1-40 +85c differential input and output impedance 250 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 SF1143B-4 yywws smp-03-s ? designed for sdars if receiver ? low insertion loss ? 5.0 x 7.0 mm surface-mount case ? differential 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 315.00 mhz saw filter SF1143B-4 pb electrical connections 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 caution: electrostatic sensitive device. observe precautions for handling. notes:
