NXPs semiconductors BGU805x series is a new family of integrated low noise amplifiers for the 300 MHz to 4 GHz range. The BGU805X series is a low noise high linearity amplifier family intended for wireless infrastructure applications like BTS, RRH, small cells, but can also be used in other general low noise applications, e.g. active antennas for automotive.
Being manufactured in NXPs high performance QUBiC RF Gen 8 SiGe:C technology, the BGU805X combines high gain, ultra-low noise and high linearity with the process stability and ruggedness which are the characteristics of SiGe:C technology. BGU805X series comes in the industry standard 2 × 2 × 0.75 mm 8 terminal plastic thin small outline package HVSON8 (SOT1327). The LNA is ESD protected on all terminals.
This application note demonstrates of the BGU8052 applied in a 1900MHz LNA for wireless infrastructure applications. The BGU8052 evaluation board is fabricated on a 35 × 20 mm 1mm thick 3 layer PCB that uses 0.2 mm (8 mill) R4003C for the RF performance. The board is fully assembled with the BGU8052, including the external components. The board is supplied with two SMA connectors to connect input and output to the RF test equipment. The EVBs are also enabled with the possibility to evaluate the BGU8052 at different bias currents
