RF Amplifier Presented as World's Smallest

June 2, 2008 6:43 am | Product Releases | Comments

Optimized for operation from 500 MHz to 12 GHz, the 0402-packaged VMMK-2x03 family of RF amplifiers is presented as the smallest such devices of their type. The 1.0 x 0.5 x 0.25-mm devices use 10% of the board area of a standard SOT-343 package and have no internal wirebonds with all I/Os routed to the backside of the device wafer to significantly reduce signal loss and minimize parasitics. The family includes the 0.5 to 6.0 GHz VMMK-2103, the 15 dB (at 5 GHz) 1.0 to 10.0 GHz VMMK-2203
