SAW Filter
The RF1400D is a low-loss, compact, and economical surface-acoustic-wave (SAW) filter
designed to provide front-end selectivity in 433.92 MHz receivers. Receiver designs using this
filter include superhet with 10.7 MHz or 500 kHz IF, direct conversion and superregen. Wider
bandwidth for channelized receiver applications.
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.

Unless noted otherwise, all measurements are made with the filter installed in the specified test fixture which is connected to a 50 Ω 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 and band-
width 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.
Where noted specifications apply over the entire specified operating temperature range of -40°C to +105°C.
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.
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.
Tape and Reel Standard Per ANSI / EIA 481.
