Qorvo QPB8958 RF Amplifiers
Qorvo QPB8958 RF Amplifiers are GaAs Pseudomorphic High Electron Mobility Transistors (pHEMT) / Metal Semiconductor Field Effect Transistor (MESFET) with 75Ω push-pull RF amplifier. These ICs are designed to support DOCSIS 3.1 applications up to 1003MHz with a single 24V supply. The QPB8958 RF amplifier ICs feature over 34dB of flat gain and 4.5dB low noise. Qorvo QPB8958 RF Amplifiers offer low noise and low distortion at a high-efficiency that consumes only 5.8W in a 5mm x 7mm QFN package. Applications include DOCSIS 3.1, broadband CATV hybrid modules, headend CMTS equipment, and 75Ω amplifiers.
