Qorvo QPL181x CATV amplifiers

Qorvo’s QPL181x amplifiers are gallium arsenide (GaAs) pseudomorphic high-electron-mobility transistor (pHEMT) CATV RF amplifiers that provide engineers with space-saving options for designs and applications within the 50 to 1800 MHz cable spectrum. Applications include cable modems, optical nodes and set-top boxes, as well as DOCSIS 4.0, fibre to the home (FTTH), GPON and GEPON communications.

The QPL1817 and QPL1816 are single-ended, 75Ω, low-noise, low-distortion CATV-RF amplifiers with 15 and 10 dB of gain, respectively. The ICs in SOT-89 configuration are suitable for infrastructure or satellite projects. The QPL1815 differential CATV amplifier is a low-noise, high-performance monolithic microwave integrated circuit (MMIC) amplifier featuring 11 dB of gain, with dual amplifiers in a push-pull configuration for good second- and third-order linearity performance. It is suitable for DOCSIS 4.0 applications.

The Qorvo QPL1812 is a single-ended, high-performance pHEMT MMIC amplifier, featuring 19 dB of gain and an active integrated bias circuit for stable gain over temperature and process variations. The QPL1811 75Ω amplifier is a broadband DOCSIS 4.0 MMIC with 16 dB gain, with two amplifiers in a push-pull configuration for robust second- and third-order linearity performance. For FTTH applications, the low-noise QPL1810 amplifier features 20 dB of flat gain and utilises a single 5 V power supply, expandable to 8 V depending on linearity requirements.
