TGA2237-SM is a broadband distributed amplifier, produced using TriQuint's SiC process with 0.25um GaN. The operating frequency of TGA2237-SM ranges from 0.03 to 2.5GHz. It offers a saturated output power of more than 10W, a signal gain of more than 13dB, and a power efficiency increase of more than 50%. TGA2237-SM features a low-cost, surface-mounted 32-lead 5x5 AIN QFN. It is highly suitable for supporting radar and communication applications in the defense and commercial markets as well as in electronic warfare. TGA2237-SM is 50Ω fully matched at both RF ports, allowing for simple system integration. Both RF ports require a DC block, and the drain voltage must be injected through the external bias three-way valve on the RF output port. Lead-free and RoHS compliant.
