Agilent MGA-53543 50 MHz to 6 GHz High Linear Amplifier
Data Sheet
Description Agilent Technologies’s MGA-53543 is a high dynamic range low noise amplifier MMIC housed in a 4-lead SC-70 (SOT-343) surface mount plastic package.
Surface Mount Package SOT-343/4-lead SC70
The combination of high linearity, low noise figure and high gain makes the MGA-53543 ideal for cellular/PCS/ W-CDMA base stations, Wireless LAN, WLL and other systems in the 50 MHz to 6 GHz frequency range.
