Nxbeam Inc., a fabless semiconductor company founded in 2018 to deliver the next generation of wireless products has developed Ku-band and Ka-band gallium nitride (GaN) monolithic microwave integrated circuit (MMIC) power amplifiers. Ideally suited for satellite communication terminals, the new MMICs provide customers with unprecedented performance in terms of output power, gain, and efficiency in a small footprint. These products are currently available in die form. Packaged versions will be available in Q3 of this year.
In the Ku-band, Nxbeam has developed the NPA1020-DE that operates from 12.5 to 14.5 GHz and provides 15 watts of saturated output power. The linear gain averages 25 dB and the average power added efficiency (PAE) is 40%. Although designed for 24 Volt operation, this part can be biased up to 28 volts where a higher saturated output power can be achieved.
In the Ka-band, Nxbeam has introduced three new MMICs. The NPA2002-DE operates from 27 to 30 GHz and provides an average saturated output power of 35 watts with 27.5 dB of linear gain, and a PAE of 27%. For extended frequency needs, Nxbeam offers the NPA2003-DE that operates from 27 to 31 GHz with an average saturated output power of 35 watts, a linear gain of 27 dB and a PAE of 26%. The third Ka-band MMIC is the NPA2030-DE that operates from 27.5 to 30.5 GHz with a saturated output power of 21 watts, a linear gain of 28 dB and a PAE of 32%.
