DOCSIS 3.1 Power Doubler Amplifier,
45 MHz to 1218 MHz
ADCA3270
Data Sheet
FEATURES
GENERAL DESCRIPTION
Drop-in replacement for RFCM3327 and RFCM3328
Total composite power: 73 dBmV
High power gain: 25 dB at 1218 MHz
Excellent linearity
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
Very low distortion
Composite triple beat: −80 dBc typical
Composite second-order: −80 dBc typical
Carrier to intermodulation noise: 59 dB typical
Low noise figure: 3 dB typical at 45 MHz and 4 dB typical at
1218 MHz
Unconditionally stable
Configurable current: 350 mA to 480 mA at 24 V
Temperature monitor
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.
