| DATA SHEET BIPOLAR ANALOG INTEGRATED CIRCUIT PC2708TB 5 V, SUPER MINIMOLD SILICON MMIC MEDIUM OUTPUT POWER AMPLIFIER DESCRIPTION The PC2708TB 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 PC2708TB has compatible pin connections and performance to PC2708T of conventional minimold version. So, in the case of reducing your system size, PC2708TB is suitable to replace from PC2708T. 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.

To supply current for output transistor, connect an inductor between the VCC pin (pin 6) and output pin (pin 4). Select large value inductance, as listed above. The inductor has both DC and AC effects. In terms of DC, the inductor biases the output transistor with minimum voltage drop to output enable high level. In terms of AC, the inductor make output-port impedance higher to get enough gain. In this case, large inductance and Q is suitable. CAPACITORS FOR THE VCC, INPUT AND OUTPUT PINS Capacitors of 1000 pF are recommendable as the bypass capacitor for the VCC pin and the coupling capacitors for the input and output pins. The bypass capacitor connected to the VCC pin is used to minimize ground impedance of VCC pin. So, stable bias can be supplied against VCC fluctuation. The coupling capacitors, connected to the input and output pins, are used to cut the DC and minimize RF serial impedance. Their capacitance are therefore selected as lower impedance against a 50 load. The capacitors thus perform as high pass filters, suppressing low frequencies to DC. To obtain a flat gain from 100 MHz upwards, 1000 pF capacitors are used in the test circuit. In the case of under 10 MHz operation, increase the value of coupling capacitor such as 10000 pF. Because the coupling capacitors are determined by equation, C = 1/(2 Rfc). 6 Data Sheet P13442EJ3V0DS00 PC2708TB ILLUSTRATION OF THE TEST CIRCUIT ASSEMBLED ON EVALUATION BOARD AMP-2 Top View 3 1 IN OUT C C 2 C 5 4 1D Mounting Direction VCC C 6 COMPONENT LIST Value C L 1 000 pF 300 nH Notes 1. 30 x 30 x 0.4 mm double sided copper clad polyimide board. 2.
