Features 1.PROFESSIONAL DESIGN: Mini bandpass filter is designed to optimize the performance of 433MHZ remote control (model airplane, drone aerial photography) receiving equipment. 2.HIGH PERFORMANCE: SAW high pass filter still has excellent suppression capability for out of band distant signals, and its performance is much better than that of products made with bare PCB. 3.INCREASED DYNAMIC RANGE: HD digital image transmission filter can effectively filter out of band signals, reduce noise, increase dynamic range, giving you the best experience. 4.CUT OFF CHARACTERISTICS OF STEEP: The filter with a low loss of interpolation, cut off characteristics of steep. It can reduce the interference from the environment, which will greatly improve the signal to noise ratio. 5.SMALL AND ROBUST: Mini 433MHZ bandpass filter is anti interference, no out of band spurious response, compact and rugged, easy to use, to meet your different needs. specificationItem Type: 433MHZ Bandpass Filter Material: Metal Interface: SMA Impedance: 50 Ohms Center Frequency: 433MHZ Maximum Carrying Power: 1W (30dBm) PackageList1 x 433MHZBandpassFilter
