Product Description
GRF2081 is a broadband, linear, ultra-low noise amplifi-
er designed for small cell, wireless infrastructure and
other high performance RF applications requiring ultra-
low NF, high gain and linearity.
Features
Reference: 5V/70mA/1.9 GHz
•

•
•
Gain: 18.5 dB
Eval Board NF: 0.41 dB
OP1dB: 19.5 dBm
OIP3: 37.5 dBm
The device features an integrated shut down function
which places the device into a high-isolation shut down
state.
GRF2081 is a member of a family of pin compatible, ul-
tra low noise devices which cover a wide range of fre-
quency bands with industry leading NF and gain:
GRF2080:
0.4 to 1.5 GHz
GRF2081:
1.4 to 2.7 GHz
GRF2082:
1.9 to 3.8 GHz
GRF2083:
3.0 to 6.0 GHz
