8.5 - 10.5 GHz 30 Watt GaN Power Amplifier: QPA1111 Datasheet
The QPA1111 is a high-power, packaged X-band MMIC amplifier fabricated using a 0.15 µm GaN-on-SiC process for reliable, high-efficiency performance in demanding applications.
The QPA1111 operates from 8.5 – 10.5 GHz, typically provides 30 W saturated output power with power-added efficiency of 45% and small signal gain of 38 dB.
To simplify system integration, the QPA1111 is fully matched to 50 ohms with DC grounded I/O ports for optimum ESD performance. Also, there are on-chip blocking capacitors following the DC grounds on the input and output ports.
The QPA1111 is ideal for supporting communications and radar applications in both commercial and military markets.
The QPA1111 is 100% DC and RF tested to ensure compliance to electrical specifications.
Lead-free and RoHS compliant.
