Text preview for : RGLNA11(2-6 GHz GaAs pHEMT).pdf part of Rficsolutions.Inc RGLNA11 The RGLNA11 is a broadband high efficiency GaAs
Enhancement mode pHEMT Low Noise Amplifier.
The device is designed for use in the 802.11a/b/g
and WLAN MIMO system.
The LNA covers a wide range of frequency from 2 to
6 GHz. The noise figure is 1.7 dB at 2.3 GHz, 1.5 dB
at 3.5 GHz and 1.5 dB at 5.5 GHz. Currently the die
size is 0.875 mm x 1mm. A single 3.3V and 37 mA
current bias the LNA. No input and output matching
components are required.
