SF2091C - 6/14/10 1. 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 ? and measured with 50 ? network analyzer. 2. rejection is measured as attenuation below the minimum il point in the passband. rejection in final user application is depen dent on pcb layout and external impedance matching design. see application note no. 42 for details. 3. the design, manufacturing process, and specifications of this filter are subject to change. 4. tape and reel standard ansi / eia 481. 5. 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. 6. us and international patents may apply. 7. rfm, stylized rfm logo, and rf monolithics, inc. are registered trademarks of rf monolithics, inc. electrical characteristics characteristic sym notes min typ max units nominal center frequency f c 1 385.00 mhz insertion loss il max 112db 1.2 db bandwidth bw 1.2 13032 mhz amplitude ripple, f c 15 mhz, within adjacent 5 mhz windows 1 1 db p-p group delay deviation, f c 15 mhz, within adjacent 5 mhz windows 1 50 ns p-p group delay deviation, f c 15 mhz, full bandwidth 1 305 ns p-p vswr at f c 12.5:1 group delay, f c 15 mhz 1 305 ns 40 db rejection bandwidth 1, 2 65 mhz operating temperature range -40 85 c case style sm5050-8 5 x 5 mm nominal footprint lid symbolization (y=year, ww=week, s=shift) rfm 593 ywws sm5050-8 ? low insertion loss 5.0 x 5.0 mm 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 +13 dbm maximum dc voltage on any non-ground terminal 30 vdc storage temperature range in tape and reel -40 to +85 c suitable for lead-free soldering - maximum soldering temperature 260 c for 30 s 385.00 mhz saw filter SF2091C pb caution: electrostatic sensitive device. observe precautions for handling. notes: electrical connections connection terminals port 1 input 1 port 2 output 5 ground all others dot indicates pin 1
