Text preview for : RGLNA01(0.7-3.0 GHz GaAs pHEMT).pdf part of Rficsolutions.Inc RGLNA01 The RGLNA01 is 0.7 to 3.0 GHz high efficiency
GaAs Enhancement mode pHEMT Low Noise
Amplifier IP Block .The device is designed for use in
the IEEE 802.11b/g, PCS, PHS and Cellular system.
The die area of RGLNA01 is 0.8 mm x 0.7 mm, with
on chip input and output matching components. This
makes it suitable for being packed in small QFN
Packages. It requires a single +3.0 Volt supply and
consumes only 15 mA current.
There is good match between the measured and
simulated results as shown below.
