Data Sheet
Description
Avago’s MGA-72543 is an economical, easy-to-use GaAs
MMIC Low Noise Amplifier (LNA),which is designed for an
adaptive CDMA receiver LNA and adaptive CDMA transmit
driver amplifier.
The MGA-72543 features a minimum noise figure of 1.4 dB
and 14 dB associated gain from a single stage, feedback
FET amplifier. The output is internally matched to 50Ω.
The input is optimally internally matched for lowest noise
figure into 50Ω. The input may be additionally externally
matched for low VSWR through the addition of a single
series inductor. When set into the bypass mode,both input
and output are internally matched to 50Ω.
The MGA-72543 offers an integrated solution of LNA with
adjustable IIP
3
. The IIP
3
can be fixed to a desired current
level for the receiver’s linearity requirements. The LNA has
a bypass switch function,which sets the current to zero
and provides low insertion loss. The bypass mode also
boosts dynamic range when high level signal is being
received.
For the CDMA driver amplifier applications, the MGA-
72543 provides suitable gain and linearity to meet the
ACPR requirements when the handset transmits the
highest power. When transmitting lower power, the MGA-
72543 can be bypassed, saving the drawing current.
The MGA-72543 is a GaAs MMIC, processed on Avago’s
cost effective PHEMT (Pseudomorphic High Electron Mo-
bility Transistor). It is housed in the SOT343 (SC70 4-lead)
package, and is part of the Avago Technologies CDMAd-
vantage RF chipset.
Attention: Observe precautions for
handling electrostatic sensitive devices.

直接存取I/O埠與記憶體(Direct access I/O and Memory)
網路上有一個工具程式名為WINIO,透過它我們可以輕易的存取記憶體與I/O埠,但是它使用了一些已經過時或未公開的函數,因為不知微軟何時會將這些函數移除,所以使用這些函數會有一定的危險性,雖然到目前32位元的Windows 7版本中還可使用。在此,我以WDK(Windows Driver Kit)的架構與相關函數,編寫一個用於存取I/O與記憶體的驅動程式,希望此程式能對您有所幫助。要重新編譯驅動程式...
