SA5205A General Description

The NE/SA/SE5205A family of wideband amplifiers replace the NE/SA/SE5205 family. The 'A' parts are fabricated on a rugged 2mm bipolar process featuring excellent statistical process control. Electrical performance is nominally identical to the original parts.

The NE/SA/SE5205A is a high-frequency amplifier with a fixed insertion gain of 20dB. The gain is flat to ±0.5dB from DC to 450MHz, and the -3dB bandwidth is greater than 600MHz in the EC package. This performance makes the amplifier ideal for cable TV applications. For lower frequency applications, the part is also available in industrial standard dual in-line and small outline packages. The NE/SA/SE5205A operates with a single supply of 6V, and only draws 24mA of supply current, which is much less than comparable hybrid parts. The noise figure is 4.8dB in a 75W system and 6dB in a 50W system. Until now, most RF or high-frequency designers had to settle for discrete or hybrid solutions to their amplification problems. Most of these solutions required trade-offs that the designer had to accept in order to use high-frequency gain stages. These include high-power consumption, large component count, transformers, large packages with heat sinks, and high part cost. The NE/SA/SE5205A solves these problems by incorporating a wide band amplifier on a single monolithic chip.

The part is well matched to 50 or 75W input and output impedances. The Standing Wave Ratios in 50 and 75W systems do not exceed 1.5 on either the input or output from DC to the -3dB bandwidth limit. Since the part is a small monolithic IC die, problems such as stray capacitance are minimized. The die size is small enough to fit into a very cost-effective 8-pin small-outline (SO) package to further reduce parasitic effects. No external components are needed other than AC coupling capacitors because the NE/SA/SE5205A is internally compensated and matched to 50 and 75W. The amplifier has very good distortion specifications, with second and third-order intermodulation intercepts of +24dBm and +17dBm respectively at 100MHz.The device is ideally suited for 75W cable television applications uch as decoder boxes, satellite receiver/decoders, and front-end mplifiers for TV receivers. It is also useful for amplified splitters and ntenna amplifiers.

The part is matched well for 50W test equipment such as signal enerators, oscilloscopes, frequency counters and all kinds of signal nalyzers. Other applications at 50W include mobile radio, CB radio nd data/video transmission in fiber optics, as well as broad-band ANs and telecom systems. A gain greater than 20dB can be chieved by cascading additional NE/SA/SE5205As in series as equired, without any degradation in amplifier stability.
