The DAT-15R5A-PN+ is a 50W RF digital step attenuator that offers an attenuation range of 15.5 dB in 0.5 dB steps. The control is a 5-bit parallel interface, operating on dual supply voltage (positive & negative). The DAT-15R5A-PN+ is produced using a unique CMOS process on silicon, offering the performance of GaAs, with the advantages of conventional CMOS devices.
