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 referenced to 0 db. rejection in final user application is dependent on pcb layout and e xternal 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. ? low insertion loss 3.8 x 3.8 mm surface-mount case single-ended input and differential output complies with directive 2002/95/ec (rohs) absolute maximum ratings rating value units maximum incident power in passband +10 dbm maximum dc voltage between any two terminals 3 vdc storage temperature range in tape and reel -30 to +85 c suitable for lead-free soldering - maximum soldering temperature 260c for 30 s 427.8 mhz saw filter SF2210D pb caution: electrostatic sensitive device. observe precautions for handling. notes: preliminary sm3838-8
