QPK1520 Octal GaN Gate Driver with Programmable Bias and Sequencing — Coming Soon!
Qorvo RF power amplifier bias controllers are ideal for radar applications
The Qorvo QPK1520 high-speed, multi-channel GaN gate bias controller is designed to provide precise, programmable gate control, sequencing, and temperature compensation for RF power amplifiers and low-noise amplifiers.
When used with the QPK1521 SPDT switch driver and QPK1522 drain controller, it forms a complete bias control chipset that enables fully coordinated gate, drain, and RF path switching in front-end modules and phased array systems. This chipset approach allows designers to implement sub-100 ns TX/RX switching, automated IDQ calibration, and safe bias sequencing, while significantly reducing the complexity and component count of traditional discrete bias networks.
Features
- 8-channel programmable gate bias control (PA + LNA support)
- Integrated DACs for independent VON/VOFF settings
- High-speed TX/RX switching with programmable sequencing
- Built-in temperature compensation for stable bias over environment
- I2C and SPI digital interface for flexible system control
- Supports IDQ calibration when paired with drain controller
- ±10 mA gate drive capability
- Compact 5 mm × 5 mm package optimized for dense array designs
Applications
- AESA radar
- Phased array systems
- Electronic warfare
- RF front-end modules (FEMs)
