ALM-81224
High Linearity 1450 – 2750 MHz Variable Gain Amplifier
Data Sheet
Description
Avago Technologies’ ALM-81224 is a high linearity vari-
able-gain amplifier module for use in the 1450-2750MHz
band. Gain control is achieved using a single DC voltage
input pin. High linearity is achieved through the use of
Avago Technologies’ proprietary GaAs Enhancement-
mode pHEMT process1. It is housed in a miniature 6.0
x 6.0 x 1.0 mm 24-pin Molded Chip On Board (MCOB)
package. Gain changes monotonically with gain control
pin voltage. Input is fully matched. Output match can be
tuned for optimal performance at a particular frequency
band within the VGA operation frequency range using
common RF board layout. The compact footprint coupled
with high linearity and efficiency makes ALM-81224 an
ideal choice for Basestation transmitters and receivers and
Temperature Compensation Circuitry applications.

Note:
1. Enhancement mode technology employs positive Vgs, thereby
eliminating the need of negative gate voltage associated with
conventional depletion mode devices.
Attention: Observe precautions for
handling electrostatic sensitive devices.
ESD Machine Model = 50 V
ESD Human Body Model = 500 V
