INTRODUCTION
Japan’s Personal Digital Cellular (PDC) service was started in 1995. Shortly after that, the service of Personal
Handy Phone Systems (PHS) was also introduced to the market. As of December, 1998, 38,998,000 cellular
subscribers and 5,981,000 PHS subscribers had signed up, accounting for 44,979,000 handsets in total and for 35.5
percent of the population.
In keeping with the trends of widespread use, the demand for handset downsizing has increased. To meet such
downsizing demands, in addition to the frequency down-converter ICs
μ
PC2757T,
μ
PC2758T, and
μ
PC8112T
currently marketed as conventional products, NEC has developed and commercialized further miniaturized 6-pin mini
mold types
μ
PC2757TB,
μ
PC2758TB, and
μ
PC8112TB.
This application note describes the usage method and selected application examples of these ICs.
