Overview of the MACOM A101/SMA1O1 Amplifier
The MACOM A101/SMA1O1 is a cascadable amplifier designed for operations within the 5 to 100 MHz frequency range. It is a hybrid amplifier leveraging thin film processes for accurate performance and reliability. The amplifier is presented with various features and packaged options including the traditional TO-8, Surface Mount, and SMA Connectorized versions, with the noted exception that the SMA Connectorized package is not RoHS compliant.
Key Features
- High output power of +23 dBm (typical)
- High third-order intercept point (IP3) of +36 dBm (typical)
- High second-order intercept point (IP2) of +64 dBm (typical)
- Low noise figure at 3 dB (typical)
