电子网9月25日消息,作为中国领先的射频及混合信号芯片供应商,锐迪科微电子(以下简称“RDA”)近日宣布推出首款国产LTE射频功率放大器与滤波器集成产品RPF5401,助力中移动B41高功率终端(以下简称“HPUE”)的普及。B41具有2496~2690MHz的较宽频带,因此能快速传输移动数据。但由于高频传输的衰减更大,所以高频段的覆盖范围明显低于中低频段;同时由于调制和发射功率的原因,终端发射的覆盖范围也明显低于接收的覆盖范围。增大
As the leading supplier of radio frequency and mixed signal chips in China, RDA (Microelectronics) announced today the launch of RPF5401, the first integrated RF power amplifier and filter integrated circuit in China, , To help China Mobile B41 high-power terminal (hereinafter referred to as “HPUE ”) popularity. B41 has a wider frequency band of 2496 ~ 2690MHz, so it can quickly transfer mobile data. However, due to the greater attenuation of high-frequency transmission, the coverage of the high frequency band is obviously lower than that of the middle and low frequency bands. At the same time, the coverage of the terminal transmission is obviously lower than that of the receiving coverage due to the modulation and the transmission power. Increase
