DIGITAL VARIABLE GAIN AMPLIFIER 30MHz - 5000MHz
The BVA303C is a digitally controlled variable gain amplifier (DVGA) and is featuring high linearity using the voltage 3V supply with a broadband frequency range of 30MHz to 5000MHz. It integrates a high performance digital step attenuator and a high linearity, broadband gain block amplifier using the small package (4x4mm QFN package) and operating voltage 3V DC. It is designed for use in 3G/4G wireless infrastructure and other high performance RF applications. Both DSA and gain block amplifier in BVA303C are internally matched to 50 Ohms and it is easy to use with no external matching components required. It always initializes to the maximum attenuation setting on power-up for both Serial and Parallel mode until next programming word is inputted. It is targeted for use in wireless infrastructure, point-to point, or can be used for any general purpose wireless application.
