SAW Filter
The RF3336 is a low-loss, compact, and economical surface-acoustic-wave (SAW) filter designed to provide
front-end selectivity in 868.35 MHz receivers. Receiver designs using this filter include superhet with
10.7 MHz or 500 kHz IF, direct conversion and superregen. Typical applications of these receivers are
wireless remote-control and security devices operating in the USA under FCC Part 15 and in Canada under
DoC RSS-210.
This coupled-resonator filter (CRF) uses selective null placement to provide suppression, typically greater
than 40 dB, of the LO and image spurious responses of superhet receivers with 10.7 MHz IF. RFM’s
advanced SAW design and fabrication technology is utilized to achieve high performance and very low loss
with simple external impedance matching (not included). Quartz construction provides excellent frequency
stability over a wide temperature range.

Unless noted otherwise, all measurements are made with the filter installed in the specified test fixture which is connected to a 50 ? test system with
VSWR ≤ 1.2:1. The test fixture L and C are adjusted for minimum insertion loss at the filter center frequency, f c . Note that insertion loss, bandwidth,
and passband shape are dependent on the impedance matching component values and quality.
The frequency f c is defined as the midpoint between the 3dB frequencies.
Unless noted otherwise, specifications apply over the entire specified operating temperature range.
The turnover temperature, T O , is the temperature of maximum (or turnover) frequency, f o . The nominal frequency at any case temperature, T c , may
be calculated from: f = f o [1 - FTC (T o - T c ) 2 ].
Frequency aging is the change in fc with time and is specified at +65°C or less. Aging may exceed the specification for prolonged temperatures
above +65°C. Typically, aging is greatest the first year after manufacture, decreasing significantly in subsequent years.
The design, manufacturing process, and specifications of this device are subject to change without notice.
One or more of the following U.S. Patents apply: 4,54,488, 4,616,197, and others pending.
All equipment designs utilizing this product must be approved by the appropriate government agency prior to manufacture or sale.
