AM55-0023

AM55-0023 V ariable 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 P1dB: +17 dBm @ 3 V, 19 dBm @ 5V Low Cost 5 mm FQFP-N Package Functional Block Diagram RF In RF Out 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.

Varying these pins between 0 and 4.5 V controls the attenuation. VCTL1 should be controlled first to avoid degrading the input match and noise figure until more attenuation is needed. VCTL1 controls an attenuator with 30 dB of range and VCTL2 15dB of range. The AM55-0023 has two sets of Vdd pins. VDDA1,2 ,3 and VDDB1,2,3. VDDA should be supplied with 5 V. This voltage is internally stepped down to 3 V to reduce current consumption. If current consumption is not a concern OR only 3 V is available to the part then the VDDB pins should be used. Using the VDDB pins with 5 V will also give greater IP3/IMD performance (See graphs). Note: When using one set of bias pins the other should be left open circuited.
