The ADPA1105 is a gallium nitride (GaN), broadband power amplifier that delivers 46 dBm (40 W) with 60% typical power added efficiency (PAE) across a bandwidth of 0.9 GHz to 1.4 GHz. The ADPA1105 provides ±0.5 dB gain flatness across a bandwidth of 0.9 GHz to 1.4 GHz. The ADPA1105 is ideal for pulsed applications such as wireless infrastructure, radar, public mobile radio, and general-purpose amplifications. The ADPA1105 comes in a 32-lead, lead frame chip scale package, premolded cavity (LFCSP_CAV).

Evaluation Kits (1)
The ADPA1105-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 ADPA1105-EVALZ are populated by Subminiature Version A (SMA) female coaxial connectors, and the respective RF traces have a 50 Ω characteristic impedance. The ADPA1105-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 two 4-pin headers (P1 and P2) and two 24-pin headers (P3 and P4) on the ADPA1105-EVALZ. The pinouts for these four headers are shown in Table 1 of the data sheet.
RF traces on the ADPA1105-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 ADPA1105-EVALZ ships with a drain pulsing board (pulser board) that can be plugged into the ADPA1105-EVALZ headers and configured to control the biasing of the ADPA1105 by providing a negative gate voltage and a control signal that connects and disconnects the drain voltage to the ADPA1105-EVALZ. The ADPA1105-EVALZ can also be operated alone in gate pulsed mode where a negative pulse is applied to the ADPA1105 VGG1 and VGG2 pins.
For full details on the ADPA1105, see the ADPA1105 data sheet, which must be consulted in conjunction with the user guide when using the ADPA1105-EVALZ.
