The RFMD RF1404D is a surface-acoustic-wave (SAW) filter operating at a center frequency of 433.92 MHz. It is designed as an ideal front-end filter for European wireless receivers, including superhet, direct conversion, and superregen designs.
Key electrical specifications include a typical insertion loss of 1.6 dB, a 3 dB bandwidth of 500-800 kHz, and significant rejection attenuation of up to 55 dB. The filter also features a temperature frequency coefficient of 0.032 ppm/°C² and an aging rate of less than 10 ppm/yr.
This coupled-resonator filter utilizes selective null placement for suppression of LO and image spurious responses. It is housed in a compact SM3838-8 case with dimensions of 3.8 x 3.8 mm and is supplied on tape and reel.
Typical applications include wireless remote-control and security devices operating under ETSI I-ETS 300 220 standards. The RF1404D is designed for simple external impedance matching.
The center frequency of the RF1404D SAW filter is 433.92 MHz at 25°C.
The typical insertion loss for the RF1404D is 1.6 dB.
The 3 dB bandwidth of the RF1404D ranges from 500 kHz to 800 kHz.
