BPF2012LM47R2400A RF Filters Application Field and Working Principle

Introduction

BPF2012LM47R2400A is a Radio Frequency (RF) filter from Murata Manufacturing Co., Ltd. This filter is part of their BPF2012 (2400-To-2484 MHz) Low Pass Band Pass Filters series. It is a filter designed for microwave communication applications such as Wi-Fi. It is designed to have a good performance across a wide frequency range of operation to provide excellent filtering in multi-channel wireless applications.

Application Field

The BPF2012LM47R2400A filter is ideal for applications in the 2400MHz to 2484MHz frequency range, and can be used in consumer wireless applications such as Bluetooth, Wi-Fi, as well as wireless local area networks (WLAN). It can also be used in mobile communication systems operating in the Global Mobile Network (GSM) range of frequencies. The filter also finds applications in other microwave communication systems such as UWB and WiMAX.

Working Principle

The filter consists of a PCB with a combination of series and parallel capacitors and inductors that are connected to form a low pass, band pass filter. The series capacitors and inductors form a low pass filter which eliminates higher frequency signals while allowing lower frequencies to pass. The parallel components form a band pass filter which eliminates lower frequencies while allowing higher frequencies to pass.The filter also has a matching network which is used to ensure an optimal signal transfer between the filter and the connected device. This is usually a combination of capacitors and inductors that is connected in series or parallel, depending on the device that is being used. This matching network will provide the best signal transfer at the frequency range that the filter is designed to operate at. The matching network can also be used to reduce unwanted noise and reduce signal losses.

Conclusion

The BPF2012LM47R2400A is a very versatile RF filter from Murata Manufacturing Co., Ltd. It can be used in many different applications in the 2400MHz to 2484MHz frequency range. It has an optimal matching network that will ensure the best signal transfer between the filter and the device being used. This filter is ideal for multi-channel wireless applications such as Bluetooth, Wi-Fi, and WLAN.
