MGA-22003
2.3-2.7 GHz 3x3mm WiMAX/WiBro
and WiFi Linear Amplifier Module
Data Sheet
Description
Avago Technologies MGA-22003 linear power amplifier is
designed for mobile and fixed wireless data applications
in the 2.3 to 2.7 GHz frequency range. The PA is optimized
for IEEE 802.16 WiMAX/WiBro modulation but can be used
for any high linearity applications. The PA exhibits flat gain
and good match while providing linear power efficiency
to meet stringent mask conditions. It utilizes Avago Tech-
nologies proprietary GaAs Enhancement-mode pHEMT
technology for superior performance across voltage and
temperature levels.
The MGA-22003 is packaged in a 3x3x1 mm package for
space-constrained applications.
Applications
• Portable WiMAX/WiBro and WiFi applications
• WiMAX/WiBro and WiFi Access points

3.3V Example :
VBCTRL = R2 *VBATT
R1 + R2
10MΩ
2.85V =
*3.3V
R1 + 10MΩ
R1 = 1.58MΩ
R2 = 10MΩ
Given :
VBCTRL = 2.85V
VBAT = 3.3V
R2 = 10M
R1 = ?
Notes: BCTRL regulates the device current, thus R1 and R2 should have
good tolerance rating. If available, a voltage regulator is the preferred
method of bias.
In this example we set R2 at 10MOhm and solve for R1 with simple voltage
divider equation. Use high resistance values to limit leakage current.
5.0V Example :
VBCTRL = R2 *VBATT
R1 + R2
10MΩ
2.85V =
*5.0V
R1 + 10MΩ
R1 = 7.54MΩ
R2 = 10MΩ
Given :
VBCTRL = 2.85V
VBAT = 5.0V
R2 = 10M
R1 = ?
