700 MHz to 3800 MHz High-Linearity Variable-Gain Amplifier

BGA7210

The BGA7210 MMIC is, also known as the BTS6001A, 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.

The BGA7210 has been designed and qualified for the severe mission profile of cellular base stations, but its outstanding RF performance and interfacing flexibility make it suitable for a wide variety of applications.

The BGA7210 is housed in a 32 pins 5 mm x 5 mm leadless HVQFN32 package.
