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.

Note:
1. The MGA-53543 has a superior LFOM of 15 dB. Linearity Figure of
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
5 V/54 mA.

Notes:
1. Measurements obtained from a test circuit described in Figure 1. Input and output tuners tuned for maximum OIP3 while keeping VSWR bet-
ter than 2:1. Data corrected for board losses.
2. I) Output power level and frequency of two fundamental tones at 1.9 GHz: F1 = 5.49 dBm, F2 = 5.49 dBm, F1 = 1.905 GHz, and F2 = 1.915 GHz.
II) Output power level and frequency of two fundamental tones at 900 MHz: F1 = -0.38 dBm, F2 = -0.38 dBm, F1 = 905 MHz, and F2 = 915 MHz.
3. Standard deviation data are based on at least 500 pieces sample size taken from 8 wafer lots. Future wafers allocated to this product may have
nominal values anywhere between the upper and lower spec limits.
