DESCRIPTION
NEC's UPC1686GV is a silicon monolithic integrated circuit
designed as a wide-band mixer/oscillator/IF amp suitable for
VHF TV/CATV tuners. Device features include: 20 dB gain
from 55 to 890 MHz and an output power of +10 dBm at
saturation. The device is available in an 8 pin SSOP package.
The nominal output impedance of the device is 75 ohms.
