BVA518
5-4000 MHz DIGITAL VARIABLE GAIN AMPLIFIER
Product Description
The BVA518 is a digitally controlled variable gain amplifier
(DVGA) is featuring high linearity using the voltage 5V
supply with a broadband frequency range of 5 to 4000
MHz.
Figure 2. Package Type
The BVA518 integrates a high performance digital step
attenuator and high performance InGaP/GaAs
HBT MMIC amplifier. Amplifier is internally matched to 50
Ohms and uses a patented temperature compensation
circuit to provide stable current over the operating tem-
perature range without the need for external components
and a patented over voltage protection circuit to protect a
internal device. The BVA518 is designed for high linearity
gain block applications that require excellent gain flatness
and designed for use in 3G/4G wireless infrastructure and
other high performance RF applications
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 BVA518 is targeted for use in wireless infrastructure,
point-to-point, or can be used for any general purpose
wireless application
