A61 / SMA61
Cascadable Amplifier
2 to 6 GHz
Features
WIDE BANDWIDTH: 2-6 GHz
MEDIUM OUTPUT LEVEL: +12.5 dBm (TYP.)
LOW NOISE: 3.2 dB (TYP.)
Description
The A61 RF amplifier is a discrete hybrid design, which uses
thin film manufacturing processes for accurate performance
and high reliability.
This single stage GaAs FET feedback amplifier design displays
impressive performance characteristics over a broadband
frequency range. An RF choke is used for DC power supply
decoupling.
Both TO-8 and Surface Mount packages are hermetically
sealed, and MIL-STD-883 environmental screening is available.
