✅ Functions

RF low-pass filter placed between antenna and RF IC in RF front-end circuit

1. Passes RF signals at 824–960MHz while suppressing 2nd and 3rd harmonics of this band.

2. Attenuates high-frequency interference at 1.7G~1.9G and 2.4G~2.8G, suppresses spurious radiation, **improves EMI performance and helps products pass EMC tests**.

3. Purifies transmitted signals and reduces outward radiated interference; meanwhile blocks external high-frequency noise from entering the receiving path to enhance receiver sensitivity.

> 

> Adopts LTCC ceramic technology with ultra-small form factor, suitable for high-density PCB design.

✅ Application Scope

The frequency band corresponds to GSM900 / LTE Band8 (880~960MHz), a commonly used band for 900MHz cellular IoT.

- IoT M2M modules, industrial wireless terminals, 900MHz data transmission modules

- Remote meter reading, asset tracking, POS wireless communication modules

- Low-power wireless communication devices, compact RF boards

> 

> Ideal for 900MHz RF solutions requiring suppression of 2.4G Bluetooth/Wi-Fi interference and resolution of harmonic overflow & EMC radiation issues.

DEA070960LT-4006B1 is a TDK LTCC RF low-pass filter with passband of 824~960MHz, designed for GSM900 / LTE Band8 IoT modules. It features low in-band insertion loss and effectively suppresses 1.8G and 2.4G harmonic interference to improve EMI radiation performance. The ultra-small 0202 package makes it well suited for the RF front-end of compact wireless terminals.
