Technical Support www.analog.com FEATURES Transmit VGA for RF DAC, transceiver, and SoC to power amplifier interface RF output frequency range: 1500 MHz to 3000 MHz Internal balun with bias-tee to supply RF DAC outputs Integrated VVA attenuation range with on-chip DAC: 20.5 dB 2-stage high linearity amplifiers RF DSA attenuation range: 15.5 dB with 0.5 dB step resolution 50 Ω differential inputs and 50 Ω single-ended output Fully programmable via a 4-wire SPI Single 5 V supply 38-terminal, 10.5 mm × 5.5 mm LGA APPLICATIONS 2G/3G/4G/long-term evolution (LTE) in FDD/TDD broadband communication systems GENERAL DESCRIPTION The ADL6317 is a transmit variable gain amplifier (VGA) that provides an interface from radio frequency digital-to-analog converters (RF DACs), transceivers, and systems on a chip (SoC) to power amplifiers. Integrated balun and hybrid couplers allow high performance RF capability in the frequency range of 1500 MHz to 3000 MHz. To optimize performance vs. power level, the ADL6317 includes a voltage variable attenuator (VVA), high linearity amplifiers, and a digital step attenuator (DSA). All of the devices integrated into the ADL6317 are programmable via a 4-wire serial port interface (SPI). The ADL6317 is manufactured on an advanced silicon germanium (SiGe), bipolar complementary metal oxide semiconductor (BiCMOS) process. Table 1.
