MGA-24106
High-Gain, Low Current Low Noise Amplifier
with Variable Current and Shutdown Function
Data Sheet
Description
Avago Technologies’ MGA-24106 is a low-noise amplifier
(LNA) designed for GPS/ISM/WiMAX applications in the
(0.9-3.5) GHz frequency range. The LNA uses Avago Tech-
nologies’ proprietary GaAs Enhancement-mode pHEMT
process to achieve high gain with very low noise figure
and high linearity. Noise figure distribution is very tightly
controlled. A CMOS-compatible shutdown pin is included
either for turning the LNA on/off, or for current adjust-
ment.
The low noise figure and high gain, coupled with low cur-
rent consumption make it suitable for use in critical low-
power GPS applications or during low-battery operation.

Notes:
1. R1, L4, C3, and C4 are not required in actual application. These are added on demoboard to mitigate power supply noise in the test
environment.
2. Pin 3 must be left unconnected.
3. L1and L2 form the input matching network. C1, C2 and L3 form a matching network at the output of the LNA.
4. Bias control is achieved by either varying the SD voltage with/ without R2, or fixing the SD voltage to Vdd and adjusting R2 for desired
current. R2 = 27 kOhm will result in 3.3mA.
