CATV amplifiers serve 50 MHz to 1800 MHz cable spectrum

The QPL181x devices 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 MHz 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 Qorvo QPL1817 and QPL1816 are single-ended, 75-ohm, low-noise, low-distortion CATV-RF amplifiers with 15dB and 10dB of gain, respectively.

These ICs in SOT-89 configuration are ideal for infrastructure or satellite projects.

Mouser also offers the QPL1815 differential CATV amplifier, a low-noise, high-performance monolithic microwave integrated circuit (MMIC) amplifier featuring 11dB of gain, with dual amplifiers in a push-pull configuration for excellent second- and third-order linearity performance.

This amplifier is ideal for DOCSIS 4.0 applications.

The Qorvo QPL1812 is a single-ended, high-performance pHEMT MMIC amplifier, featuring 19dB of gain and an active integrated bias circuit for stable gain over temperature and process variations.

The QPL1811 75-ohm amplifier is a broadband DOCSIS 4.0 MMIC with 16dB gain, with two amplifiers in a push-pull configuration for robust second- and third-order linearity performance.

For FTTH applications, Mouser stocks the low-noise QPL1810 amplifier, which features 20dB of flat gain and utilises a single 5V power supply, expandable to 8V depending on linearity requirements.

The QPL181x amplifiers are each supported by corresponding evaluation and development kits also available from Mouser Electronics.

Each devices' development kit features a pre-mounted amplifier along with support circuitry and connectors for rapid prototyping.
