| DATA SHEET DATA SHEET BIPOLAR ANALOG INTEGRATED CIRCUIT PC1678G 5 V-BIAS, +17.5 dBm OUTPUT, 2.0 GHz WIDEBAND Si MMIC AMPLIFIER DESCRIPTION The PC1678G is a silicon monolithic integrated circuit designed as medium output power amplifier for high frequency system applications. Due to +17.5 dBm TYP. output at 2 GHz, this IC is recommendable for transmitter stage amplifier of L BAND wireless communication systems. This IC is packaged in 8-pin plastic SOP. This IC is manufactured using NEC's 20 GHz fT NESATTMIV 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.

A internal matching circuit, configured with resisters, enables 50 connection over a wide band. A multi-negative feedback circuit is designed to cancel the deviations of hFE and resistance. This pin must be coupled to signal source with capacitor for DC cut. Ground pin. This pin should be connected to system ground with minimum inductance. Ground pattern on the board should be formed as widely as possible. All the ground pins must be connected together with wide ground pattern to decrease impedance difference. Signal output pin.

To supply current for output transistor, connect an inductor between the VCC pin (pin 8) and output pin (pin 5). 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 1 800 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, 1 800 pF capacitors are used in the test circuit. In the case of under 100 MHz operation, increase the value of coupling capacitor such as 10 000 pF. Because the coupling capacitors are determined by equation, C = 1/(2 Rfc).
