BeRex BVA305C
The BVA305C is a digitally controlled variable gain amplifier (DVGA) is featuring high linearity using the voltage 3V supply with a broadband frequency range of 40MHz to 5000MHz. The BVA305C 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 . Both DSA and gain block amplifier in BVA305C are internally matched to 50 Ohms and It is easy to use with no external matching components required.| Part No. | BVA305C |
