GRF2505
Broadband LNA/Linear Driver
4.0 to 6.0 GHz
Product Description
GRF2505 is a broadband, ultra-low noise, linear amplifi-
er offering the highest levels of performance for de-
manding 802.11ac and wireless backhaul LNA and PA
driver applications.
This amplifier exhibits outstanding broadband NF, linear-
ity and return losses over 4.0 to 6.0 GHz with a single
match. It is operated from a single positive supply of
1.8V to 5.0 V with a selectable Iddq range of 20 to 60
mA for optimal efficiency and linearity.
GRF2505 is internally matched to 50Ω at the input and
output ports, requiring only 7 external RLC components.
Consult with the GRF applications engineering team for
custom tuning/evaluation board data and device s-
parameters
