PHEMT Low Noise Amplifier

PHEMT* Low Noise Amplifier with Bypass Switch Technical Data MGA-72543 Features • Lead-free Option Available • Operating Frequency 0.1 GHz ~ 6.0 GHz • Noise Figure: 1.4 dB at 2 GHz • Gain: 14 dB at 2 GHz • Bypass Switch on Chip Loss = -2.5 dB (Id < 5 µ A) IIP3 = +35 dBm • Adjustable Input IP3 +2 to +14 dBm • 2.7 V to 4.2 V Operation • Very Small Surface Mount Package Surface Mount Package SOT-343 (SC-70) figure into 50Ω. The input may be additionally externally matched for low VSWR through the addition of a single series inductor. When set into the bypass mode, both input and output are internally matched to 50Ω. The MGA-72543 offers an integrated solution of LNA with adjustable IIP3. The IIP3 can be fixed to a desired current level for the receiver’s linearity requirements. The LNA has a bypass switch function, which sets the current to zero and provides low insertion loss. The bypass mode also boosts dynamic range when high level signal is being received. For the CDMA driver amplifier applications, the MGA-72543 provides suitable gain and linearity to meet the ACPR requirements when the handset transmits the highest power. When transmitting lower power, the MGA-72543 can be bypassed, saving the drawing current. The MGA-72543 is a GaAs MMIC, processed on Agilent’s cost effective PHEMT (Pseudomorphic High Electron Mobility Transistor). It is housed in the SOT343 (SC70 4-lead) package, and is part of the Agilent Technologies CDMAdvantage RF chipset. Pin Connections and Pac.
