Ideal for Ka-Band radar and electronic warfare designs operating within 32 to 38 GHz

Qorvo’s TGA2222 is a high-frequency, wide band power amplifier MMIC fabricated on Qorvo’s production 0.15 um GaN on SiC process (QGaN15). Covering 32 – 38 GHz, the TGA2222 provides 40 dBm (10 W) of saturated output power and 16 dB of large-signal gain while achieving > 22% power-added efficiency.

The TGA2222 employs a balanced architecture to minimize performance sensitivity to load variation. Its RF ports are DC coupled to ground for optimum ESD performance. The TGA2222 has DC blocking capacitors on both RF ports, which are matched to 50 ohms.

The TGA2222 also finds uses in satellite communication systems. A balanced architecture minimizes performance sensitivity to load variation and RF ports are DC coupled to ground for optimum ESD performance. With the advantages of GaN on SiC fabrication, the device draws 640 mA from a 26 V supply and is offered as a 3.4 x 2.6 mm DIE.
