ALM-81224 - AVAGO

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

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.
