Agilent MGA-71543 Low Noise Amplifier with Mitigated Bypass Switch
Data Sheet
Features • Operating frequency: 0.1 GHz ~ 6.0 GHz • Noise figure: 0.8 dB (NFmin) • Gain: 16 dB • Average Idd = 2mA in CDMA handset Description Agilent’s MGA-71543 is an economical, easy-to-use GaAs MMIC Low Noise Amplifier (LNA), which is designed for adaptive CDMA and W-CDMA receiver systems. The MGA-71543 is part of the Agilent Technologies complete CDMAdvantage RF chipset. The MGA-71543 features a minimum noise figure of 0.8 dB and 16 dB available gain from a single stage, feedback FET amplifier. The input and output are partially matched, and only a simple series/shunt inductor match is required to achieve low noise figure and VSWR into 50Ω. When set into the bypass mode, both input and output are internally matched through a mitigative circuit. This circuit draws no current, yet duplicates the in and out impedance of the LNA. This allows the system user to have minimum mismatch change from LNA to bypass mode, which is very important when the MGA-71543 is used between duplexers and/or filters. The MGA-71543 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 provides low insertion loss at zero current. The bypass mode also boosts dynamic range when high level signal is being received. The MGA-71543 is designed for CDMA and W-CDMA receiver systems. The IP3, Gain, and mitigative network are tailored to these applications where filters are used. Many CDMA systems operate 20% LNA mode, 80% bypass. With the bypass current draw of zero and LNA of 10 mA, the MGA-71543 allows an average 2 mA current. The MGA-71543 is a GaAs MMIC, processed on Agilent’s cost effective PHEMT (Pseudomorphic High Electron Mobility Transistor Technology). It is housed in the SOT343 (SC70 4-lead) package. • Bypass switch on chip Loss = -5.6 dB (Id < 5 µA) IIP3 = +35 dBm • Adjustable input IP3: 0 to +9 dBm • 2.7 V to 4.2 V operation Applications • CDMA (IS-95, J-STD-008) Receiver LNA • Transmit Driver Amp • W-CDMA Receiver LNA • TDMA (IS-136) handsets Surface Mount Package SOT-343/4-lead SC70
