The NXP BGA7204 and BGA7210 are monolithic digital variable-gain amplifiers (VGAs) that operate over an extremely wide range with high linearity and high output power. Designed for the transmit path of wireless architectures, these VGAs can be used to control the power level to the power amplifier. The up-converted signals are fed to the VGA, and thus help compensate for variations in cell load and the presence of aging infrastructure equipment. The BGA7204 operates in the range between 0.4 and 2.75 GHz, while the BGA7210 operates between 0.7 and 3.8 GHz. By supporting more than 2 GHz of bandwidth, these devices can be used to populate several frequency bands. An integrated power-save mode makes it possible to reduce consumption even more, to just 15 mA during a receive slot. This can effectively reduce the current consumption in Time Division Duplexing (TDD) systems up to 45%. Schematic of BGA7210 evaluation board (OM7921) The BGA7210 builds on the BGA7204 by adding flexible current setting across its two amplifiers, depending on the attenuation state. The serial peripheral interface is used to set the attenuation state, and, using a similar method, to set the current through the first and second amplifiers. The desired configuration is set by software and enables current savings of as much as 75 mA. Higher output power, higher peak gain, and smaller attenuator step sizes enable engineers to use fewer components and provide greater control to maintain and optimize performance in the transmit chain. Smart routing (with no connection crosses) reduces the number of board connections, simplifies design-in, and decreases the design footprint by 25%.
