ALM-81224 - High Linearity 1450 - 2750 MHz Variable Gain Amplifier

General Description

Avago Technologies’ ALM-81224 is a high linearity variable-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 Enhancementmode pHEMT process1.

ALM-81224 High Linearity 1450 – 2750 MHz Variable Gain Amplifier Data Sheet Description Avago Technologies’ ALM-81224 is a high linearity variable-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 Enhancementmode 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.
