Push-pull amplifier operates from 50 to 1218 MHz, making it suitable for DOCSIS 3.1
Richardson RFPD Inc. announced the availability and full design support capabilities for a pHEMT dual RF amplifier from Qorvo.
The TAT7472A1F is a 75 Ω RF amplifier designed for CATV use but capable of operation up to 1218 MHz, making it suitable for DOCSIS 3.1. It contains two separate amplifiers for push-pull applications and is fabricated using 6-inch GaAs pHEMT technology to optimize performance and cost. Each amplifier contains on-chip active biasing, with bias current set points that are adjustable with a single resistor from the input to ground.
Typical supply voltage for the TAT7472A1F is +5 V; IMD performance and bandwidth can be enhanced with +5.5 V and +6 V operation.
The device is suitable for DOCSIS 3.1 applications, including Edge QAM gain stage, mains distribution unit (MDU) output, RF distribution amplifiers, and AH22S-G replacement.
According to Qorvo, additional key features of the TAT7472A1F include:
- Low noise figure: <3 dB
- Gain: 15 dB
- CSO: -80 dBc @ 450 MHz
- CTB: -74 dBc @ 450 MHz
- +41 dBmV / channel
- SOIC-8 package
