Compared to the SOT-6/SOT-63 packages usually used for high-power switches, NEC’s SC-70/SOT-363-style TB package offers a 48% reduction in footprint and a 31% reduction in maximum height, providing increased flexibility for size-constrained designs. It operates at frequencies from 0.5 to 2.5 GHz with low harmonic distortion. Insertion loss is 0.35 dB (typical) at 0.9 GHz and 0.40 dB (typical) at 1.8 GHz. Second harmonics is rated at 70 dB at 0.9 and 1.8 GHz, while third harmonics is 75 dB at 0.9 and 1.8 GHz.

In stock and available now from California Eastern Laboratories (CEL), the UPG2155TB is priced at $0.40 in 100K quantities. To help speed circuit design, evaluation boards are available through CEL sales offices as well as from Mouser Electronics.
