Nokia Siemens Networks Flexi Multiradio BTS is a GSM/EDGE, WCDMA/(I-)HSPA, and LTE base station for use in mobile telecommunication antenna networks. A network that you use daily on your cellphone.

This is the 4th part of a video series on this system, all high resolution pictures at the website http://kaizerpowerelectronics.dk/teardown/nokia-siemens-networks-flexi-wcdma-teardown-power-amplifier-part-4/

Part 1: System station http://kaizerpowerelectronics.dk/teardown/nokia-siemens-networks-flexi-wcdma-teardown-system-station-part-1-of-3/
Part 2: Power Amplifier http://kaizerpowerelectronics.dk/teardown/nokia-siemens-networks-flexi-wcdma-teardown-power-amplifier-part-2-of-3/
Part 3: Antenna http://kaizerpowerelectronics.dk/teardown/nokia-siemens-networks-flexi-wcdma-teardown-antenna-part-3-of-3/

The following 25 minute video shows the part 4 teardown step by step with explanations, high resolution pictures of content can be found on the links above.

I did a further part on the integrated Doherty amplifier IC itself.  Teardown of a NXP BLD6G22L-150 integrated Doherty amplifier from a Nokia Siemens Networks Flexi WCDMA base station.
