Qorvo QPK1520 Octal GaN Gate Driver - Coming Soon
Qorvo QPK1520 Octal Gallium Nitride (GaN) Gate Driver is a high-speed, multi-channel GaN gate bias controller. Ideal for RF power amplifiers and low-noise amplifiers, this Qorvo driver provides precise, programmable gate control, sequencing, and temperature compensation. When used with the QPK1521 single-pole double-throw (SPDT) switch driver and QPK1522 drain controller, the QPK1520 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-100ns TX/RX switching, automated IDQ calibration, and safe bias sequencing, while significantly reducing the complexity and component count of traditional discrete bias networks.
