The RRU3928 is an outdoor remote radio unit. It processes baseband and RF signal data. With the Software Defined Radio (SDR)technology, the RRU3928 supports the dual-mode operation of any two modes of GSM, UMTS, and LTE through software configuration modification. RRU3928 has a dual-transmitter and dual-receiver structure, which supports higher output power and carrier capacity.

It can f.ex. do 6x GSM carriers at each 10 Watt and 1x LTE carrier at 2x10 Watt or 4x GSM carrier at each 10 Watt and 2x UMTS carriers at 2x20 Watt.

This is the initial teardown and later on I will release part 2 which is the circuit analysis video.

Here is the part 2 video, the circuit analysis of the amplifier.



I can unfortunately not upload the high resolution pictures here on the forum, so you can see those on my website: http://kaizerpowerelectronics.dk/teardown/huawei-rru3928-1800mhz-radio-base-station-circuit-analysis-part-2-of-2/
