ADPA1113 - 2-6GHz 46dBm GaN Power Amplifier | Analog Devices
MPN: ADPA1113 ✓ فعالADPA1113 جائزہ
A GaN power amplifier is a high-efficiency RF amplifier that uses gallium nitride transistors to achieve high output power and wide bandwidth. GaN technology offers superior power density, thermal performance, and efficiency compared to traditional silicon-based amplifiers, making it ideal for demanding RF applications. In the signal chain hierarchy, the ADPA1113 functions as a final-stage power amplifier, converting low-level RF signals into high-power signals suitable for transmission, typically following driver amplifiers and preceding antennas or filters.
Key features of the ADPA1113 include its 46.5 dBm saturated output power, 39.0% PAE, and operation across the full 2.3 GHz to 5.7 GHz band without external matching. The device is biased with a positive 28 V drain supply and a negative gate voltage, enabling precise control of the quiescent current. The 14-lead LDCC package provides excellent thermal performance, with the exposed pad facilitating heat transfer to the PCB. The amplifier is recommended for new designs, indicating active lifecycle status and ongoing manufacturer support.
Technically, the ADPA1113 utilizes a cascaded gain stage architecture, allowing it to achieve high gain and output power in a single device. The negative gate bias (VGG1) sets the operating point, ensuring linearity and efficiency across the frequency range. The device's broadband performance eliminates the need for external matching networks, reducing design complexity and component count. The 28 V drain supply is typical for GaN devices, balancing efficiency and output power.
Typical applications include radar systems, electronic warfare, communications infrastructure, and test and measurement equipment. The ADPA1113's high output power and wide bandwidth make it suitable for pulsed and continuous-wave (CW) operation in these systems. Its efficiency reduces thermal management requirements, enabling compact system designs.
When designing with the ADPA1113, ensure proper thermal management through adequate PCB copper area and heat sinking, as the device dissipates significant power at high output levels. The negative gate bias must be applied before the drain supply to prevent device damage, following standard GaN biasing sequences.

ڈیزائن نوٹس
The ADPA1113 requires a 28 V drain supply and a negative gate bias on VGG1. Apply the negative gate voltage first to set IDQ to 750 mA before enabling the drain supply. This sequencing prevents inrush current and potential device damage. Use a low-impedance 28 V supply capable of handling the peak current during RF drive.
At 46.5 dBm output with 39% PAE, the ADPA1113 dissipates significant power. For example, at 44.7 W output and 39% PAE, input power is approximately 114.6 W, resulting in ~70 W of heat dissipation. Ensure adequate thermal management using the exposed pad soldered to a large copper area with thermal vias. Consider a heatsink or forced air cooling for continuous operation.
The ADPA1113 requires no external matching, but proper PCB layout is essential. Use 50-ohm controlled impedance traces for RF input and output. Place decoupling capacitors close to the drain supply pins. The exposed pad must be soldered to the ground plane for thermal and electrical performance. Follow the layout guidelines in the datasheet for optimal performance.
