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.

ADPA1106主要特性:

► Frequency range: 2.7 GHz to 3.5 GHz

► POUT: 46 dBm typical with PIN = 21 dBm at 2.7 GHz to 3.1 GHz

► Power gain: 25 dB typical with PIN = 21 dBm at 2.7 GHz to 3.1 GHz
