A70 Datasheet, PDF (1/2 Pages) Tyco Electronics – 10 TO 250 MHz CASCADABLE AMPLIFIER

A70 / SMA70
Cascadable Amplifier
10 to 250 MHz
Rev. V3
Features
• VERY LOW NOISE: 1.6 dB (TYP.)
• HIGH EFFICIENCY +8.0 dBm (TYP.)
OUTPUT POWER AT 10 mA (TYP.)
Description
The A70 RF amplifier is a discrete hybrid design, which uses
thin film manufacturing processes for accurate performance and
high reliability.
This single stage bipolar transistor feedback amplifier design
displays impressive performance over a broadband frequency
range. Use of an impedance transformer offers the benefit of
high dynamic range and high efficiency.
Both TO-8 and Surface Mount packages are hermetically
sealed, and MIL-STD-883 environmental screening is available
