MGA-61563-BLKG (BROADCOM LIMITED)

The MGA-61563-BLKG is an easy-to-use high linearity current-adjustable Low Noise Amplifier built-in with smart bias function. For smart bias function, one external resistor is used to set the bias current taken by the device over a wide range. This allows the designer to use the same part in several circuit positions and tailor the linearity performance and current consumption to suit each position. It is ideal as a LNA or driver amplifier for cellular/PCS/W-CDMA base stations, WLL, fixed wireless access, wireless LAN and other high performance applications in the 0.1 to 6GHz frequency range. The MGA-61563 is normally operating with Id set in the 20 to 60mA range. The output of the amplifier is matched to 50R (below 2:1 VSWR) across the entire bandwidth and only requires minimum input matching. The amplifier allows a wide dynamic range by offering a 1.2dB NF coupled with a +28.5dBm output IP3. The circuit uses state-of-the-art E-PHEMT technology with proven reliability.
