ELECTRICAL CHARACTERISTICS

* Undesired = Desired 12 MHz, 30% 100 kHz AM S/I Ratio = 46 dB

FEATURES

DESCRIPTION

• WIDE-BAND OPERATION: DC to 890 MHz

• SMALL PACKAGE

• DOUBLE BALANCED MIXER:

• BALANCED AMPLIFIER FOR VOLTAGE

• SINGLE ENDED PUSH-PULL IF AMPLIFIER:

• SWITCHABLE AS MIXER OR IF AMP

The UPC1687 is a silicon monolithic integrated circuit de-

signed as a wide-band mixer/oscillator/IF amp suitable for

UHF TV tuners. Device features include: 25 dB gain from 55

to 890 MHz and an output power of +10 dBm at the saturation

point. The device is available in an 8 pin mini-flat package. The

nominal output impedance of the UPC1687G is 75 ohms.
