Qorvo’s QPA3311 and QPA3316 hybrid energy doubler amplifiers are optimized for DOCSIS 4.0 downstream operations as much as 1.8 GHz. They help the transition to Unified DOCSIS and good amplifier architectures that improve visibility, effectivity, and adaptableness in hybrid fiber-coax (HFC) methods.
Primarily based on a GaAs/GaN die, the gadgets function from 45 MHz to 1794 MHz and supply 23 dB of acquire. They’re well-suited for DOCSIS 4.0 CATV nodes and amplifiers. Excessive whole composite energy and improved sign integrity cut back cascade necessities and improve end-of-line efficiency, serving to decrease infrastructure prices by eliminating the necessity for booster amps.
The QPA3311 and QPA3316 energy doublers function from 24-V and 34-V provides, respectively, with energy consumption of 12.5 W and 18 W. At 51 dB CNN, whole composite energy reaches 74 dBmV for the QPA3311 and over 75 dBmV for the QPA3316.
Each the QPA3311 and QPA3316 energy doubler amplifiers are housed in SOT-115J packages and are actually in manufacturing.
