BVA304
50-4000 MHz DIGITAL VARIABLE GAIN AMPLIFIER
Product Description
The BVA304 is a digitally controlled variable gain amplifier
(DVGA) is featuring high linearity using the voltage 3.3V
supply with a broadband frequency range of 50 to 4000
MHz.
The BVA304 integrates with a high performance digital
step attenuator and a high linearity broadband gain block.
It using the small package(4x4mm QFN package), and
operating VDD 3.3V voltage.
Also it designed for use in 3G/4G wireless infrastructure
and other high performance RF applications.
Amplifier used in BVA304 is a high performance InGaP/
GaAs HBT MMIC amplifier, internally matched to 50 Ohms
and uses a patented temperature compensation circuit to
provide stable current over the operating temperature
range without the need for external components.
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 BVA304 is targeted for use in wireless infrastructure,
point-to-point, or can be used for any general purpose
wireless application
