433MHZ -5-0DBm Low Pass 2.4GHZ-2.6GHZ Elliptical Filters S6R5 The low pass filter allows signals the cutoff frequency to pass, while signals above the cutoff frequency are attenuated. It is often used for the suppression of higher harmonics of electromagnetic signals, or it is placed at the back end of the mixer to filter out high frequency clutter, which plays the role of frequency selection. This filter can greatly attenuate signals above 470M, and the harmonic suppression capability is about 50dbc.Compared with several low-pass filters, elliptical filters can achieve narrower transition bandwidths and smaller values than other types of filters, such as Butterworth and Chebyshev filters, under the same order. The stop band fluctuates. In this regard, the elliptical filter is optimal. This is a 7th-order elliptic function low-pass filter with better filtering steepness than other filters.1, S11 Less than -20dB, standing wave ratio SWR Less than 1.22;2, S22 Less than -20dB, standing wave ratio SWR Less than 1.22;3, S21Greater than -0.5dB, insertion loss Less than 0.5dB;4, PCB dimensions (without sma connector): 36mm x 16mmColour:greenMaterial:plasticPackage Contents:1 x 433MHZ low pass filter
