SF2027B-041403 Electrical Characteristics Characteristic Sym Notes Min Typ Max Units Nominal Frequency fN 1 199.0 MHz Insertion Loss (including matching to 200 ohms) IL < 7.0 dB Group Delay Ripple, peak - peak (198.9 .. 199.1 MHz) < 700 ns Amplitude Ripple, peak - peak (198.9 .. 199.1 MHz) < 1.0 dB Relative attenuation fn - 100 kHz .. fn +100 kHz (passband) < 0.7 fn - 300 kHz, fn +300 kHz > 10 dB fn - 500 kHz, fn +500 kHz > 27 dB fn - 600 kHz, fn +600 kHz > 36 dB <fn - 700 kHz,> fn +700 kHz > 45 dB Case Style SMP-53-S 13.3 X 6.5 mm Nominal Footprint Lid Symbolization (Y=year, WW=week, S=shift) See note 4 RFM SF2027B YWWS SMP-53-S • GSM BTS Receiver IF Applications • Small Size • Hermetic 13.3 X 6.5 mm Surface Mount Case Input power Level short test +18 dBm standard operation, max +10 dBm Max DC Voltage between any 2 terminals 10V Input: possible for balanced and unbalanced operation (TBD) Output: Balanced External matching to 50 or 200 ohms 199.0 MHz SAW Filter SF2027B 1. Unless noted otherwise, all specifications apply over the operating temperature range with filter soldered to the specified demonstration board with impedance matching to 50 Ω and measured with 50 Ω network analyzer. A dB offset exists for RFM because of the loss introduced by using transformers on the Input and Output. 2. Rejection is measured as attenuation below the minimum IL point in the pass- band. Rejection in final user application is dependent on PCB layout and exter- nal impedance matching design. See Application Note No. 42 for details. 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 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. 8. ©Copyright 1999, RF Monolithics Inc. 9.
