GENERAL DESCRIPTION

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).
