A low-pass filter is a filter that passes signals with a frequency lower than a selected cutoff frequency and attenuates signals with frequencies higher than the cutoff frequency. These filters are usually applied after RF amplifiers (MMIC, Gain-block and Class C amplifiers) for suppression of high-order harmonics of radio-frequency signals, or placed at the mixer output to filter out high-frequency interference that plays a role in frequency selection. An Elliptic filter (also known as a Cauer filter), compared with others filters such as Butterworth and Chebyshev of equal order can have a faster transition in gain between the passband and the stopband. If you are ordering a custom filter, in the ordering note, specify the cutoff frequency in [MHz] at -3dB level in the range of 1 – 1000 MHz. Сutoff frequency: choose in the selector 1 – 1000 MHz; Low Insertion Loss S21: 0.5 – 1dB; Standing wave ratio VSWR (S11, S22): 1.1 – 1.3; PCB Dimensions (without SMA connectors): 35mm x 30mm; LPF can be set for specific custom frequency Or you can select desired frequencies from optional list: CUSTOM FREQUENCY 1-1000MHz LPF 1Mhz LPF 1.8Mhz LPF 3.5Mhz LPF 7Mhz LPF 10Mhz LPF 14Mhz LPF 15Mhz LPF 18Mhz LPF 20Mhz LPF 21Mhz LPF 28Mhz LPF 30Mhz LPF 40Mhz LPF 50Mhz LPF 70Mhz LPF 72Mhz LPF 100Mhz LPF 144Mhz LPF 200Mhz LPF 230Mhz LPF 250Mhz LPF 300Mhz LPF 315Mhz LPF 400Mhz LPF 433Mhz LPF 470Mhz LPF 500Mhz LPF 600Mhz LPF 700Mhz LPF 800Mhz LPF 868Mhz LPF 900Mhz LPF 915Mhz LPF 1Ghz
