The ADL6331 transmit variable gain amplifier (TxVGA) provides an interface from RF digital-to-analog converters (RF DACs) to a singled-ended power amplifier (PA) signal chain. Each ADL6331 IC is composed of a balun, two differential RF amplifiers with bypass attenuators, and a digital step attenuator (DSA) to provide suitable transmitter performance in a 24-terminal, 4.0 mm x 4.0 mm LGA package.
Serial-port interface (SPI) control is available to configure RF signal paths or to optimize supply current vs. performance.
An integrated RF balun is used to provide a single-ended output over 0.38 GHz to 8.0 GHz (ADL6331-A) or 1.0 GHz to 15.0 GHz (ADL6331-B) with good impedance match.
