BVA303
30-4000 MHz DIGITAL VARIABLE GAIN AMPLIFIER
Product Description
The BVA303 is a digitally controlled variable gain amplifier
(DVGA) is featuring high linearity using the voltage 3V
supply with a broadband frequency range of 30 to 4000
MHz.
Figure 2. Package Type
The BVA303 integrates a high performance digital step
attenuator and a high linearity, broadband gain block.
using the small package(4x4mm QFN package) and oper-
ating VDD 3V voltage.
and designed for use in 3G/4G wireless infrastructure and
other high performance RF applications
24-lead 4x4 mm QFN
Both stages are internally matched to 50 Ohms and It is
easy to use with no external matching components re-
quired
A serial output port enables cascading with other serial
controlled devices.
An integrated digital control interface supports both serial
and parallel programming of the attenuation,
including the capability to program an initial attenuation
state at power-up.
Covering a 31.5 dB attenuation range in 0.5 dB steps.
The BVA303 is targeted for use in wireless infrastructure,
point-to-point, or can be used for any general purpose
wireless application
