AM55-0023
Variable Voltage Gain Control Amplifier
0.8 - 2.0 GHz
Features
• Highly Integrated Variable Voltage Gain Control Amplifier
• Operates with 3.0 V to 5 V Supply Voltage
• Greater than 40 dB dynamic range
• High Output P_1dB: +17 dBm @ 3 V, 19 dBm @ 5V

Description
M/A-COM’s AM55-0023 is a high performance, voltage
controlled, variable gain amplifier. It has been designed for use
in a broad range of applications including cellular base stations
and mobile radio where AGC is required to increase system
dynamic range.
The gain control operates best in the 900 MHz range and also
has useable gain to 2.5 GHz. DC current is low at 160 mA at
3V bias and 200 mA at 5V bias. The package is a low cost
MLF.
The AM55-0023 is fabricated using M/A-COM’s 0.5 micron
low noise GaAs MESFET process. The process features full
passivation for performance and reliability.
