OR:  

The BGA7210 MMIC is an extremely linear Variable Gain Amplifier (VGA), operating from 0.7 GHz to 3.8 GHz. The maximum gain is 30 dB. It has an attenuation range of 31.5 dB. At its minimum attenuation setting it has a maximum output power of 21 dBm, an IP3O of 39 dBm and a noise figure of 6.5 dB. The current consumption can be optimized per attenuation setting allowing for optimized overall system performance. The current consumption and attenuation level are controlled through a Serial Peripheral Interface (SPI). The current can be reduced to 120 mA. Optimal linearity performance is obtained at 185 mA. The BGA7210 has a fast switching power-down pin to further reduce current consumption during idle time.
