.RF filters are components in electronic systems designed to provide signal filtering or signal conditioning. The LFD18620MDP9C091 is an example of an RF filter, designed specifically for cellular and mobile radio applications. It is also suitable for other high frequency applications requiring a combination of low insertion loss with out-of-band rejection.
The LFD18620MDP9C091 is a two-element multiplexer filter designed for use in GSM/EDGE networks. It is suitable for both EGSM up to 2.14GHz and DCS up to 1.88GHz. The filter consists of two parallel-coupled ceramic resonators, a balanced network between them, and a complex impedance matching network. The double-balun structure and the power divider minimize the size of the filter, and improve the linearity and dynamics of the system.
The filter provides low insertion loss of less than 0.3 dB, with an excellent out-of-band rejection level of more than 60 dB. The GSM/EDGE networks are very demanding systems in terms of out-of-band interference levels; thus, the LFD18620MDP9C091 can be an ideal solution for such applications. It is designed to have a steady-state balance and high linearity, resulting in a better signal purity and a greater operational efficiency.
The working principle of the LFD18620MDP9C091 is based on the action of two parallel-coupled resonators. The resonators create a signal that passes through two narrower passbands separated by a wider stopband, before being sent onwards to the next device. The filter is designed to stimulate the passbands of the appropriate GSM services, while rejecting frequent interferers at the same time.
The filter can be easily implemented with surface mount devices, as it only requires a single IC and a few discrete components. This reduces the overall production cost by eliminating the need for high-cost cables and connectors. Additionally, the filter can be used in various cellular/mobile radio systems where high out-of-band rejection is required, such as GSM/EDGE, NetPCS, GPRS/EDGE, DECT, and Other CDMA systems.
In conclusion, the LFD18620MDP9C091 multiplexer filter is an ideal solution for high-frequency applications where low-insertion loss and high out-of-band rejection are needed. It is suitable for GSM/EDGE networks up to 2.14GHz and DCS up to 1.88GHz. The filter can be integrated into a single IC with surface mount devices, resulting in a cost-effective solution. Additionally, it provides excellent linearity and dynamics, high out-of-band rejection, and reliable operation.
