BeRex BVA3143
The BVA3143 is a digitally controlled variable gain amplifier (DVGA) in a 6mm x 6mm LGA package, with a frequency range of 3300 to 3800 MHz and an operating VDD of 5.0V. BVA3143 is high performance and high dynamic range makes it ideally suited for use in 5G/LTE wireless infrastructure and other high performance wireless RF applications. The BVA3143 is an integration of a high performance digital 7bit step attenuator (DSA) that provides a 31.75 dB attenuation range in 0.25 dB steps, and high linearity broadband gain block amplifiers featuring high ACP and P1dB.| Part No. | BVA3143 |

DESCRIPTION
The BVA3143 digital control interface supports serial programming of the attenuator, and includes the reference gain (max gain, bypass) state on the Parallel programing . The BVA3143 is integrated of two gain blocks (AMP1, AMP2), a digital step attenuator (DSA) and high linearity amplifier (AMP3). Implementation requires only a few external components, such as matching capacitors on the Input and Output pins. (Don’t need DC Blocking Capacitor) Figure 1. Functional Block Diagram Figure 2.
