Low power digital wideband VGAs feature high linearity
The BGA7210 is the only device of its kind capable of working as a VGA up to 4 GHz without external matching. Both VGAs feature NXP’s smart routing lead design, which simplifies PCB placement and reduces the footprint of the device by 25 percent.
Designed primarily for use in wireless infrastructure equipment, the VGAs from NXP ensure that the incoming signal is always at optimum strength by compensating for any degradation caused by changes in temperature. By controlling the power level to the power amplifier, the VGAs also help compensate for variations in cell load and the presence of aging infrastructure equipment.
The BGA7204 and BGA7210 devices perform with better power consumption than competitive offerings, with several power-saving features, including a unique power-save mode that can effectively reduce the current consumption in TDD systems up to 45 percent. The BGA7210 also adds flexible current distribution across its two amplifiers, depending on the attenuation state, to save power.
The BGA7204 has a frequency band from 400 MHz to 2.8 GHz while the BGA7210 features a frequency band from 700 MHz to 3.8 GHz.
