RF filters are electronic components used to filter out specific frequency signals or block them from entering a circuit. The 2450BP41D100AE is a switched bandwidth RF filter designed specifically for ISM band applications. It enables fractional bandwidth capabilities, and features a wide rejection band for maximum performance. As a part of the product\'s active filtering technology, it utilizes an integrated passive element combined with active compensation circuitry.

Specifically, this RF filter measures 4.0x1.5x1.2mm and has a typical insertion loss of ≈ 2.0dB, with a minimum rejection of –40dB. It operates over a 1.89-2.04GHz frequency range and can be tuned to achieve up to 20dB of rejection. The digital-controlled filter was designed to enable frequency agility in mobile communication systems. It offers a wide array of features, including low distortion, low insertion loss, high attenuation in wide operation bandwidths, fast switching time, monotonic group delay, and small mechanical size.

The 2450BP41D100AE is suitable for use in TD-SCDMA, and has been tested to meet stringent industry specifications in 4G and legacy 3G mobile communication systems. It can be used in other wireless applications, such as Global Positioning Systems (GPS), Wifi, Wireless Local Area Network (WLAN), Bluetooth, ZigBee, ISM, Vsat, Digital Television, Measurement systems, Avionics, and Radars.

The 2450BP41D100AE utilizes an integrated five-element configuration that uses capacitors and resistors to fabricate its filter characteristics. This design offers superior performance by allowing for both fast switching speeds and improved isolation. Its active compensation circuit compensates for varying component values, allowing for high linearity and low distortion. Additionally, the filter can be adjusted using an external voltage for tuning in frequency bands that are far from its center frequency, allowing for maximum flexibility.

In operation, the 2450BP41D100AE uses a three-stage approach for power handling, amplification, and filtering. First, the power is amplified and then passed through the filter, allowing only frequencies that are within a desired range to pass. Finally, the filtered signal is passed through the amplifier, resulting in an output that is clean and free of any unwanted frequencies. This ensures that the desired signal is amplified without interference from any external sources.

Overall, the 2450BP41D100AE is a versatile and powerful RF filter that can be used in a variety of different applications and can serve as an ideal choice for those seeking fast switching speeds and improved isolation in a fractional bandwidth filter. In addition to its wide variety of features, its small size, low distortion, and low insertion loss also make it a great choice for those seeking optimum performance in their ISM-band applications.
