A74-2 Datasheet, PDF (1/2 Pages) Tyco Electronics – Cascadable Amplifier 5 to 500 MHz

Cascadable Amplifier
5 to 500 MHz
Features
• AVAILABLE IN SURFACE MOUNT
• HIGH GAIN - TWO STAGES: 26 dB (TYP.)
• LOW POWER DRAIN 65 m W AT 5 VOLTS
Description
The A74-2 RF amplifier is a discrete hybrid design, which uses
thin film manufacturing processes for consistent performance
and high reliability.
This 2 stage bipolar transistor feedback amplifier design
displays impressive performance over a broadband
frequency range. An active DC biasing network insures
temperature-stable performance.
Both TO-8 and Surface Mount packages are hermetically
sealed, and MIL-STD-883 environmental screening is available
