QPL1822 75 15dB CATV Amplifier (50 1800MHz) Product Overview The QPL1822 is an ultra-linear, GaAs pHEMT, differential RF amplifier. The device features a cascode design which provides 15dB of flat gain along with very low distortion from 50MHz to 1.8GHz. This ultra-linear IC is designed to support Broadband CATV DOCSIS 4.0 applications, such as Nodes, Amplifiers, and Remote PHY Devices, as well as Fiber to The Home (FTTH), Home Gateways, and Cable Modems. The device is powered by a single 5V supply at 260mA which provides an output of 63dBmV TCP at an MER of 45dB. The QPL1822 is 2 packaged in a 12-pin 5x5 mm Laminate Module. 5 x 5 12pin Laminate MCM Package Functional Block Diagram Key Features 50MHz to 1800MHz Operation 5V & 8V Operation Gain: 15dB Typical TCP: 63dBmV 5V TCP: 67dBmV 8V Noise Figure: 2.5/4dB 50/1800MHz Adjustable Bias Using External Resistors RoHS Compliant Applications DOCSIS 4.0 Amplifiers DOCSIS 4.0 Optical Nodes DOCSIS 4.0 Remote PHY Devices FTTH GPON and GEPON DOCSIS 4.0 Cable Modem and Home Gateways 5 x 5 12pin Laminate MCM Package Ordering Information Part Number Description QPL1822EVB-01 Evaluation Board QPL1822SB Sample bag with 5 pieces QPL1822SR 7 Reel with 100 pieces QPL1822TR13 13 Reel with 2500 pieces Data Sheet Rev A, Jan 10, 2022 Subject to change without notice - 1 of 13 - QPL1822 75 15dB CATV Amplifier (50 1800MHz) 0 Absolute Maximum Ratings Parameter Rating Supply Voltage (VDD) +10V Supply Current (IDD) 400mA Maximum Input Level +65 dBmV Operating Temperature Range -40 to +100C Storage Temperature Range 65 to +150C Maximum Junction Temperature +150C Exceeding any one or a combination of the Absolute Maximum Rating conditions may cause permanent damage to the device.
