Product Details
The Analog Devices, Inc., ADCA3270 is a 24 V power doubler, monolithic microwave IC (MMIC) with 25 dB of power gain. The device achieves high RF output up to 73 dBmV composite power under 18 dB tilt conditions by using advanced circuit design techniques with gallium arsenide (GaAs), pseudomorphic high electron transistor (pHEMT), and gallium nitride (GaN) HEMT technologies. The dc current and supply voltage can be adjusted externally for optimum distortion performance vs. power consumption over a range of output levels. The ADCA3270 provides high gain, simplifying the design and manufacturing of DOCSIS 3.1 infrastructure equipment.
The ADCA3270 is packaged in a 9-terminal thermally enhanced chip array small outline no lead cavity [LGA_CAV] with an industry-standard footprint.
