71 MHz

SAW Filter

The SF1046 is designed as a low cost IF filter for GSM digital mobile phone applications.

The SF1046 utilizes RFM’s advanced SAW design and fabrication technology to achieve

high performance, low loss, and simple source/load matching. Quartz construction

provides excellent frequency stability over a wide operating temperature range.

NOTES:

1. Specifications are referenced to f_o= 71.00 MHz. Bandwidth specifications include manufacturing frequency tolerance and frequency drift over temperature

range T_A.

2. Specifications are given with filter matched to 50 ohms. Input match (pin 1) is 330 nH ±2% series L with 75pF ±5% shunt C on 50 ohm side; output match

(pin 8) is 440 nH ± 2% series L with 75pF ±5% shunt C on 50 ohm side. Nominal inductor Q is 50 at 71 MHz.

3. Ultimate rejection specified from 1 to 110 MHz. Spurious responses at 1.6 and 1.8 times f_osuppressed by matching networks.

4. The following U.S. Patents apply: 4,353,046 and 5,073,763. Specifications subject to change without notice.

5. Specifications subject to change without notice.

6. RFM® is registered in the US Patent and Trademark office.
