The PC8178TK is a silicon monolithic integrated circuit designed as amplifier for mobile communications. This IC can realize low current consumption with external chip inductor which can not be realized on internal 50 wide band matched IC. PC8178TK adopts 6-pin lead-less minimold package using same chip as the conventional PC8178TB in 6-pin super minimold. TK suffix IC which is smaller package than TB suffix IC contributes to reduce mounting space by 50 %. This IC is manufactured using our 30 GHz fmax UHS0 (Ultra High Speed Process) silicon bipolar process.
