IF output

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.
