描述 Description

The ABA3130 is a low noise amplifier with gain control that accepts a single-ended RF input in the 50 MHz to 1.1 GHz frequency range and provides a balanced RF output with minimal degradation in signal quality. This highly integrated device amplifies the input signal using a highly linear, low noise amplification stage. The overall linearity is maintained across a wide gain control range, ensuring low distortion effects on the output signal. Requiring a single +5 V supply, the ABA3130 design is implemented using highreliability GaAs MESFET process. The small, surface mount QFN packaging makes this device ideal for use in Cable TV set-top boxes and television receiver front-ends.
