μPB1508GV is a 3.0 GHz input divide by 2 prescaler IC for DBS tuner applications. μPB1508GV can make VHF/UHF band PLL frequency synthesizer apply to DBS/ECS tuners. μPB1508GV is a shrink package version of μPB584G so that this small package contributes to reduce the mounting space.

μPB1508GV is manufactured using NEC’s high fT NESAT? IV silicon bipolar process. This process uses silicon nitride passivation film and gold electrodes. These materials can protect chip surface from external pollution and prevent corrosion/migration. Thus, this IC has excellent performance, uniformity and reliability.
