Analog Devices Inc. ADL6317 Transmit Variable Gain Amplifier
Analog Devices ADL6317 Transmit Variable Gain Amplifier provides an interface from radio frequency digital-to-analog converters, transceivers, and systems on a chip (SoC) to power amplifiers. The device is ideal for 2G/3G/4G/long-term evolution (LTE) in FDD/TDD broadband communication systems. The ADL6317 VGA features integrated balun and hybrid couplers that allow high-performance RF capability in the 1500MHz to 3000MHz frequency range. The device includes a voltage variable attenuator (VVA), high linearity amplifiers, and a digital step attenuator (DSA) to optimize performance-vs.-power level.
Features
- Transmit VGA for RF DAC, transceiver, and SoC to power amplifier interface
- 1500MHz to 3000MHz RF output frequency range
- Internal balun with bias-tee to supply RF DAC outputs
- Integrated VVA attenuation range with on-chip DAC: 20.5dB
- 2-stage high linearity amplifiers
- RF DSA attenuation range: 15.5dB with 0.5dB step resolution
- 50Ω differential inputs and 50Ω single-ended output
- Fully programmable via a 4-wire SPI
- Single 5V supply
- 38-terminal, 10.5mm × 5.5mm LGA
Applications
- 2G/3G/4G/long-term evolution (LTE) in FDD/TDD broadband communication systems
