pHEMT dual RF amplifier targets CATV
A new pHEMT dual RF amplifier from Qorvo is in stock at distributor Richardson RFPD. The TAT7472A1F is a 75Ω 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 optimise 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 +5V; IMD performance and bandwidth can be enhanced with +5.5V and +6V operation.
The new 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 of <3 dB and gain of 15 dB. The devices comes in a SOIC-8 package.
