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 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 75Ω system and 6dB in a 50Ω system.
