PC2776TB
5 V, SUPER MINIMOLD SILICON MMIC MEDIUM OUTPUT POWER AMPLIFIER
DESCRIPTION
The PC2776TB is a silicon monolithic integrated circuits designed as wideband amplifier. This amplifier has impedance near 50 in HF band, so this IC suits to the system of HF to L band. This IC is packaged in super minimold package which is smaller than conventional minimold. The PC2776TB has compatible pin connections and performance to the PC2776T of conventional minimold version. So, in the case of reducing your system size, the PC2776TB is suitable to replace from the PC2776T. These IC is manufactured using NEC's 20 GHz fT NESATTM III 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.

Remarks Typical performance. Please refer to ELECTRICAL CHARACTERISTICS in detail. Notice The package size distinguishes between minimold and super minimold. Selection point among product line-up
PC2709TB: Suits to 1 GHz 2.5 GHz operation due to small inductance (e.g. 10 nH) between VCC and output pin. PC2776TB: Suits to HF to 2.0 GHz operation due to large inductance (e.g. 100 nH) between VCC and output pin.

INDUCTOR FOR THE OUTPUT PIN The internal output transistor of this IC consumes 20 mA, to output medium power. 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 1 000 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, 1 000 pF capacitors are used in the test circuit. In the case of under 10 MHz operation, increase the value of coupling capacitor such as 10 000 pF. Because the coupling capacitors are determined by equation, C = 1/(2Rfc).

NOTE ON CORRECT USE (1) Observe precautions for handling because of electro-static sensitive devices. (2) Form a ground pattern as wide as possible to minimize ground impedance (to prevent undesired oscillation). All the ground pins must be connected together with wide ground pattern to decrease impedance difference. (3) The bypass capacitor (e.g. 1 000 pF) should be attached to VCC pin. (4) The inductor must be attached between VCC and output pin (e.g. 100 nH) (5) The DC cut capacitor must be each attached to the input and output pins.

While NEC Corporation has been making continuous effort to enhance the reliability of its semiconductor devices, the possibility of defects cannot be eliminated entirely. To minimize risks of damage or injury to persons or property arising from a defect in an NEC semiconductor device, customers must incorporate sufficient safety measures in its design, such as redundancy, fire-containment, and anti-failure features. NEC devices are classified into the following three quality grades: "Standard", "Special", and "Specific". The Specific quality grade applies only to devices developed based on a customer designated "quality assurance program" for a specific application. The recommended applications of a device depend on its quality grade, as indicated below. Customers must check the quality grade of each device before using it in a particular application. Standard: Computers, office equipment, communications equipment, test and measurement equipment, audio and visual equipment, home electronic appliances, machine tools, personal electronic equipment and industrial robots Special: Transportation equipment (automobiles, trains, ships, etc.), traffic control systems, anti-disaster systems, anti-crime systems, safety equipment and medical equipment (not specifically designed for life support) Specific: Aircrafts, aerospace equipment, submersible repeaters, nuclear reactor control systems, life support systems or medical equipment for life support, etc. The quality grade of NEC devices is "Standard" unless otherwise specified in NEC's Data Sheets or Data Books. If customers intend to use NEC devices for applications other than those specified for Standard quality grade, they should contact an NEC sales representative in advance. Anti-radioactive design is not implemented in this product.
