SF2050A-120705 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. "lrip" or "l" after the part number indicates "low rate initial production" and "eng" or "e" indicates "engineering prototypes." 4. the design, manufacturing process, and specifications of this filter are subject to change. 5. 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. 6. us and international patents may apply. 7. rfm, stylized rfm logo, and rf monolithics, inc. are registered trademarks of rf monolithics, inc. 8. ?copyright 1999, rf monolithics inc. 9. electrostatic sensitive device. observe precautions for handling. electrical characteristics characteristic sym notes min typ max units center frequency f c 1 44.00 mhz insertion loss 18.00 db rejection 1db min, frequency lower 42.3 mhz 1db min, frequency upper 45.7 bandwidth, 38db min 10.70 10 38db min, frequency lower 39.00 38db min, frequency upper 49.00 15 to 39mhz 38 40 db 49 to 75mhz 38 42 db group delay (across 1 db frequencies) 100 150 nsec pk-pk amplitude ripple (across 1 db frequencies) 0.5 1 dbpk-pk reflected wave signal suppression 1 usec after main pulse 20 30 2 usec after main pulse 30 40 3 usec after main pulse 40 50 input impedance (differential) 1000 ohms output impedance (differential) 1000 ohms temperature operating -40 85 c storage -40 85 case style 9 x 5 mm nominal footprint lid symbolization (yy=year, ww=week, s=shift) see note 4 rfm SF2050A yywws ? designed for 802.16 and wimax receiver if application ? low insertion loss ? 5.0 x 9.0 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 +13 dbm max. dc voltage between any 2 terminals 30 vdc storage temperature range -40 to +85 c suitable for lead-free soldering - max soldering profile 260c for 30 s 44.00 mhz saw filter SF2050A pb
