DESCRIPTION
NEC's UPC2756TB is a silicon MMIC integrated circuit manu-
factured using the NESAT III process. The device consists of
a double balance mixer, an IF amplifier and a built-in LO. this
device is suitable as a L-BAND downconverter for the receiver
stage of wireless systems. The UPC2756TB is pin compatible
and has comparable performance as the larger UPC2756T, so
it is suitable for use as a replacement to help reduce system
size. The IC housed in a 6 pin super minimold or SOT-363
package.
NEC's stringent quality assurance and test procedures ensure
the highest reliability and performance.

Ground pin. This pin should be
connected to system ground with
minimum inductance. Ground
pattern on the board should be
formed as wide as possible.
These pins are both the base-
collectors of a differential amplifier
configured to oscillate when
equipped with an external tank
resonator circuit. Each pin must be
coupled to the tank circuit with a
blocking capacitor. In the case of
an external LO source, bypass the
unused pin with a capacitor to
ground.
