The 0868LP15A020E is a high-Q, low pass filter optimized for the 860–870 MHz frequency range. Ideal for use in LTE base station receivers, this filter offers a steep roll-off, low insertion loss (typical 0.9 dB insertion loss), high power handling capability of up to 50 W, and excellent harmonic attenuation (typical ≥45 dBc). The filter requires only a single-supply voltage of +15 Vdc, uses a dual-discrete topology, and is available in a convenient package size.

The 0868LP15A020E filter can be classified as an RF filter due to its function in communication systems. It is used in a variety of applications including LTE base station receivers, high-frequency amplifiers, and local oscillators.

The primary function of the 0868LP15A020E filter is to filter out unwanted signals and noise. It works by passing a frequency range of 860-870 MHz and attenuating all the signals outside of this range. The filter has a sharp roll-off which helps to provide a high level of performance in suppressing unwanted spectral components. Additionally, the filter has high harmonic attenuation which helps to suppress any noise generated from products that could interfere with the filter’s performance.

The working principle of the filter is based on a combination of inductors and capacitors. The inductors are responsible for providing low-frequency attenuation and high-frequency passband, while the capacitors are responsible for providing a bandpass shape with a sharp roll-off. The components are arranged in a way that minimizes losses and maximizes signal isolation. The filtered signal is then output from the filter’s output port.

The 0868LP15A020E is a valuable tool for many applications that require a filter for eliminating unwanted signals and noise. Its combination of high-performance components, attractive package size, and excellent power handling capability make it an ideal choice for those needing a low pass filter for 860-870 MHz frequency range.
