DESCRIPTION
The NE/SA/SE5205A family of wideband amplifiers replace the NE/SA/SE5205 family. The ‘A’ parts are fabricated on a rugged 2µm 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 20d B. The gain is flat to ±0.5d B from DC to 450MHz, and the -3d B 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 24m A of supply current, which is much less than parable hybrid parts. The noise figure is 4.8d B in a 75Ω system and 6d B in a 50Ω 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 ponent 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 75Ω input and output impedances. The Standing Wave Ratios in 50 and 75Ω systems do not exceed 1.5 on either the input or output from DC to the -3d B 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...
