MGA-53543
50 MHz to 6 GHz High Linear Amplifier
Data Sheet
Description
Avago 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.
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.
MGA-53543 is especially ideal for Cellular/PCS/ W-CDMA
basestation applications. With high IP3 and low noise
figure, the MGA-53543 may be utilized as a driver ampli-
fier in the transmit chain and as a second stage LNA in
the receive chain.

Merit (LFOM) is essentially OIP3 divided by DC bias power. There
are few devices in the market that can match its combination of
high linearity and low noise figure at the low DC bias power of
5V/54 mA.
Attention:
Observe precautions for handling electrostatic
sensitive devices.
