DESCRIPTION
The UPC1678 is a silicon monolithic integrated circuit de-
signed as a wide-band amplifier covering the HF to UHF
bands. The device features high output power, 18 dBm TYP,
high gain, 23 dB TYP and operates from a single 5 volt supply.
The UPC1678 is available in two package styles: 8 pin SOP
and SSOP packages.
NEC's stringent quality assurance and test procedures ensure
the highest reliability and performance.
