The ACA1240 is a 1.2 GHz variable gain CCAP/edge QAM driver amplifier specifically designed for CATV Applications. This GaAs based amplifier 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 more than 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 O using balun transformers.
It operates from a single 12 V supply and consumes up to 6 watts of power. The amplifier has superior output power and gain performance, as well as unparalleled linearity to meet critical downstream RF specifications (DRFI) at a higher power level. It is available in an 11 x 11 mm surface-mount package.
