Skyworks has introduced its latest CATV solution, the ACA1240, a 1.2 GHz variable gain CCAP/edge QAM driver amplifier specifically designed for headend and remote PHY applications.
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 O 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.
The ACA1240 features industry-leading return loss over attenuation range minimizing passband ripple, thus enabling optimal filter performance. In addition, this amplifier offers superior output power and gain performance, as well as unparalleled linearity to meet critical downstream RF specifications (DRFI) at a higher power level.
