GRF2374
Low Current LNA w/Bypass
Tuning Range: 0.1 to 3.8 GHz
Product Description
GRF2374 is a low noise amplifier (LNA) with bypass de-
signed for high-performance WLAN/ISM and other appli-
cations up to 3.8 GHz. Ideal for low power, cost sensi-
tive bypass amplifier applications.
Features
Reference: 3.3V/15mA/2.4 GHz
•
•
•
•
EVB NF: 1.4 dB
Gain: 14.0 dB
Bypass Gain: -2.0 dB
OP1dB: 10.0 dBm
The LNA is operated from a single positive supply of 2.7
to 5.0 V with typical bias condition of 3.3 volts and 15
mA.
Consult with the GRF applications engineering team for
custom tuning/evaluation board data and device s-
parameters.
