The ADPA1106 is a gallium nitride (GaN), broadband power amplifier that delivers 46 dBm (40 W) with 56% typical power added efficiency (PAE) across a bandwidth of 2.7 GHz to 3.1 GHz. The ADPA1106 has a gain flatness of ±0.15 dB across the 2.7 GHz to 3.1 GHz frequency range.
The ADPA1106 is ideal for pulsed applications such as marine, weather, and military radar.
The ADPA1106 comes in a 32-lead, lead frame chip scale package, premolded cavity (LFCSP_CAV) and is specified for operation from −40°C to +85°C.

Evaluation Kits (1)
The ADPA1106-EVALZ consists of a 2-layer printed circuit board (PCB) fabricated from a 10 mil thick, Rogers 4350B copper clad mounted to an aluminum heat spreader. The heat spreader assists in providing thermal relief to the device as well as mechanical support to the PCB. Mounting holes on the heat spreader allow the spreader to be attached to a heat sink. Alternatively, the spreader can be clamped to a hot and cold plate. The RFIN and RFOUT ports on the ADPA1106-EVALZ are populated by Subminiature Version A (SMA) female coaxial connectors, and the respective RF traces have a 50 Ω characteristic impedance. The ADPA1106-EVALZ is populated with components suitable for use over the entire operating temperature range of the device. To calibrate board trace losses, a through calibration path is provided between the J6 and J5 connectors. J6 and J5 must be populated with SMA RF connectors to use the through calibration path.
Ground, power, gate control, and the detector output voltage are provided through the two 24-pin headers (P4 and P5) on the ADPA1106-EVALZ. The pinouts for these two headers are shown in Table 1 of the user guide.
RF traces on the ADPA1106-EVALZ are 50 Ω, grounded, coplanar waveguide. The package ground leads and the exposed paddle connect directly to the ground plane. Multiple vias connect the top and bottom ground planes with particular focus on the area directly beneath the ground pad to provide adequate electrical conduction and thermal conduction to the heat spreader.
The ADPA1106-EVALZ ships with a drain pulser board that can be plugged into the ADPA1106-EVALZ headers and configured to control the biasing of the ADPA1106 by providing a negative gate voltage and a control signal that connects and disconnects the drain voltage to the ADPA1106-EVALZ. The ADPA1106-EVALZ can also operate alone in gate pulsed mode where a negative pulse is applied to the VGG1 and VGG2 pins of the ADPA1106.
For full details on the ADPA1106, see the ADPA1106 data sheet, which must be consulted in conjunction with the user guide when using the ADPA1106-EVALZ.
Tools & Simulations
ADI has always placed the highest emphasis on delivering products that meet the maximum levels of quality and reliability. We achieve this by incorporating quality and reliability checks in every scope of product and process design, and in the manufacturing process as well. "Zero defects" for shipped products is always our goal.
