Broadband LNA/Linear Driver
Tuning Range: 3.0 to 6.0 GHz

The GRF2505 is a broadband, ultra-low noise, linear amplifier offering the highest levels of performance for demanding 802.11ac and wireless backhaul LNA and PA driver applications. This amplifier exhibits outstanding broadband NF, linearity and return losses over 3.0 to 6.0 GHz with a single match. It is operated from a single positive supply of 1.8 V to 5.0 V with a selectable Iddq range of 20 to 60 mA for optimal efficiency and linearity.

GRF2505 is internally matched to 50 Ω at the input and output ports, requiring only 7 external RLC components.
