MGA-43228
(2.3–2.5) GHz 29dBm High Linearity Wireless Data Power Ampli er
Data Sheet
Description
Avago Technologies’ MGA-43228 is a power ampli er for
use in the (2.3-2.5)GHz band. High linear output power
at 5V is achieved through the use of Avago Technologies’
proprietary 0.25um GaAs Enhancement-mode pHEMT
process. It is housed in a miniature 5.0mm x 5.0mm x
0.85mm 28-lead QFN package. It also includes shutdown
and switchable gain functions. A detector is also included
on-chip. The compact footprint coupled with high gain
and high e ciency make the MGA-43228 an ideal choice
as a power ampli er for IEEE 802.16 (WiMAX) and WLL
applications.

Note:
1. Enhancement mode technology employs positive Vgs, thereby
eliminating the need of negative gate voltage associated with
conventional depletion mode devices.

Application Schematic
Notes:
1. In normal gain mode operation, Vbyp = 0V. Vc1, Vc2 and Vc3 are bias pins that are used to set the bias conditions to the 3 internal gain stages of
the PA.
2. Typical quiescent current distribution with Vdd1 = Vdd2 = Vdd3 = Vbias = 5V, Vbyp = 0V, Vc = 2.1V is :
a. Idd1 = 50 mA
b. Idd2 = 180 mA
c. Idd3 = 270 mA
d. Ibias = 16.5mA
(Note: Vc supplied through Vc2 pin on demonstration board with R2 = 1.2k , R3 = 300 and R4 = 1.2k)
3. Low gain mode is enabled by setting Vbyp pin to 5V. This condition overrides the normal high gain mode operation and bypasses the rst gain
stage, regardless of the voltage at Vc1 pin.
4. Modulated signal measurements are made with Agilent 89600 VSA and Agilent E4438C signal generator with IEEE 802.16e option using the
following test conditions :
– Signal format: IEEE 802.16e OFDMA, ¾ rate FEC
– Modulation: 64-QAM
– Number of Subcarriers: 840
– Modulation bandwidth: 10 MHz
– Downlink ratio: 50%
Residual distortion of signal generator: (0.6-0.8)%. This distortion is not removed from the overall EVM data in the datasheet.
5. Typical operating voltages and currents:
a. Normal gain mode: Vdd1 = Vdd2 = Vdd3 = Vbias = 5V. Vc = 2.1V. Vbyp = 0V. Iq(total) = 500 mA.
b. Low gain mode: Vdd1 = Vdd2 = Vdd3 = Vbias = 5V. Vc = 2.1V. Vbyp = 5V. Iq(total) = 500 mA.
6. Vdd1/2/3 are shown as separate supplies with individual bypass capacitors. This yields the most stable con guration. If a common power supply
line is used, proper broadband bypass decoupling is recommended to reduce common mode feedback through the supply line.
