This highly integrated device amplifies the input signal using a highly linear, low noise amplification stage. Alternately, it can be used as a signal attentuator using the appropriate gain/attenuation control voltage. The overall linearity is maintained across a wide gain Bias Supply Bias RF Input GND control range, ensuring low distortion effects on the output signal. Requiring a single +5 V supply, the ABA3130 design is implemented using ANADIGICS’ own high-reliability GaAs MESFET process. The small, surface mount QFN packaging makes this device ideal for use in Cable TV set-top boxes, television receiver front-ends, and other low noise applications. The device is characterized for both 75 V and 50 V systems.
