Advance Information
The RF Small Signal Line
GaAs MESFET AGC Amplifier
The MRF9820T1 is a high performance GaAs AGC amplifier suitable for use
in low noise front end amplifier or downconverter applications. The device
contains two enhancement mode MESFETs connected in cascode to allow
access to both gates for gain control or injection of LO signals. This device is
well suited for low voltage, low current front–end applications such as paging,
cellular, GSM, DECT, and other portable wireless systems.
