| SF1087A * * * * * * Designed for GSM BTS Transmitter IF Applications Low Insertion Loss Excellent Size-to-Performance Ratio Hermetic 13.3 x 6.5 mm Surface-Mount Case Unbalanced Input and Output Pb Complies with Directive 2002/95/EC (RoHS) 208 MHz SAW Filter Value +10 30 -40 to +85 260C for 30 s Units dBm VDC C Absolute Maximum Ratings Rating Maximum Incident Power in Passband Max. DC voltage between any 2 terminals Storage Temperature Range Suitable for lead-free soldering - Max. Soldering Profile SM13365-12 Electrical Characteristics Characteristic Nominal Center Frequency Passband Insertion Loss at fc 1 dB Passband Amplitude Ripple over fc150 kHz Group Delay Variation over fc 150 kHz Absolute Group Delay Rejection fc-0.6 to fc-0.4 and fc+0.4 to fc+0.6 MHz fc-1.2 to fc-0.6 and fc+0.6 to fc+1.2 MHz fc-1.8 to fc-1.2 and fc+1.2 to fc+1.8 MHz fc-3.4 to fc-1.8 and fc+1.8 to fc+3.4 MHz fc-9.5 to fc-3.4 and fc+3.4 to fc+9.5 MHz fc-13 to fc-9.5 and fc+9.5 to fc+13 MHz DC to fc-13 and fc+13 to 450 MHz Except Spurious Rejection near 1.6, 1.8, and 2.0 x fc Operating Temperature Range Impedance Matching to 50 unbalanced Case Style Lid Symbolization (YY = year, WW = week) Notes: 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 W and measured with 50 network analyzer. 2. Unless noted otherwise, all frequency specifications are 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 dependent 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 initial production" and "ENG" or "E" indicates "engineering prototypes." 5. The design, manufacturing process, and specifications of this filter are subject to change. 6. 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. 7. US and international patents may apply. 8. Electrostatic Sensitive Device. Observe precautions for handling.
