Please note: this product is being discontinued and is not recommended for new designs. The ACA1240 is a GaAs based amplifier that contains highly linear amplification and attenuation stages for use in CATV CCAP/EQAM/CMTS modulators and networks. It incorporates a continuously adjustable linear attenuator that is controlled by an external analog voltage. This glitch-free attenuator provides a minimum of 20 dB of continuously variable attenuation and is preceded by a high-linearity pre-amplifier and followed by a high-gain output driver. Both input and output are matched to 75 Ω using balun transformers. The ACA1240 operates from a single 12 V supply and is offered in an 11 mm x 11 mm surface-mount package.
