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.
VCTL2
VCTL1
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.
Ordering Information
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.

Variable Voltage Gain Control Amplifier, 2.0 GHz
Operating Instructions
Two pins, VCTL1 and VCTL2 control the attenuation function
of this part. 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).
