UPC1678G Datasheet | NEC

DESCRIPTION The µPC1678G is a silicon monolithic integrated circuit designed as medium output power amplifier for high frequency system applications. Due to +17.5 d Bm TYP. output at 2 GHz, this IC is remendable for transmitter stage amplifier of L BAND wireless munication systems. This IC is packaged in 8-pin plastic SOP. This IC is manufactured using NEC’s 20 GHz f T 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. FEATURES - Supply voltage - Saturated output power - Wideband response - Power gain - Isolation : VCC = 4.5 to 5.5 V : PO(sat) = +17.5 d Bm TYP. @ f = 500 MHz with external inductor : fu = 2.0 GHz TYP. @ 3 d B bandwidth : GP = 23 d B TYP. @ f = 500 MHz : ISL = 35 d B TYP. @ f = 500 MHz APPLICATIONS - PA driver for high frequency system.
