BVA2140

Preliminary Datasheet 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 amplifier (DVGA) in a small 4x4mm QFN package, with a broadband frequency range of 700 to 4000 MHz and an operating 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 wireless applications. The BVA2140 is an integration of a high performance digital 6-step attenuator (DSA) that provides a 31.5 dB attenuation 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 programming 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...
