DESCRIPTION

The µPC2708TB is a silicon monolithic integrated circuit designed as buffer amplifier for BS/CS tuners. This IC is packaged in super minimold package which is smaller than conventional minimold.

The µPC2708TB has compatible pin connections and performance to µPC2708T of conventional minimold version. So, in the case of reducing your system size, µPC2708TB is suitable to replace from µPC2708T.

This IC is manufactured using NEC’s 20 GHz fT NESATTM lll silicon bipolar process. This process uses silicon nitride passivation film and gold electrodes. These materials can protect chip surface from external pollution and prevent corrosion/migration. Thus, this IC has excellent performance, uniformity and reliability.

FEATURES

• High-density surface mounting : 6-pin super minimold package (2.0 × 1.25 × 0.9 mm)

• Wideband response : fu = 2.9 GHz TYP. @ 3 dB bandwidth

• Medium output power : PO(sat) = +10 dBm TYP. @ f = 1 GHz with external inductor

• Supply voltage : VCC = 4.5 to 5.5 V

• Power gain : GP = 15 dB TYP. @ f = 1 GHz

• Port impedance : input/output 50 Ω

APPLICATIONS

• 1st IF amplifiers in BS/CS converters, etc.

• 1st IF stage buffer in BS/CS tuners, etc.
