BVA2140
0.7- 4GHz 1/4W Medium Power DIGITAL VARIABLE GAIN AMPLIFIER
Product Description
Figure 2. Package Type
The BVA2140 is a digitally controlled variable gain amplifi-
er (DVGA) in a small 4x4mm QFN package, with a broad-
band frequency range of 700 to 4000 MHz and an oper-
ating VDD of 5.0V at 150mA.
BVA2140 is high performance and high dynamic range
makes it ideally suited for use in WCDMA/LTE wireless
infrastructure point-to-point and other demanding wire-
less applications.
The BVA2140 is an integration of a high performance digi-
tal 6-step attenuator (DSA) that provides a 31.5 dB attenu-
ation range in 0.5 dB steps, and high linearity broadband
gain block amplifiers featuring high ACLR and P1.
The BVA2140 digital control interface supports serial pro-
gramming of the attenuator, and includes the ability to
define the initial attenuation state at power-up.
Implementation requires only a few external components,
such as DC blocking capacitors on the Input and Output
pins, plus a bypass capacitor and a RF choke for the Output
port.
