MGA725M4

The MGA725M4 is designed as one kind of economical, easy-to-use GaAs MMIC Low Noise Amplifier (LNA) that belongs to the MGA725 family. This device (1)CDMA (IS-95, J-STD-008) receiver LNA; (2)transmit driver amp; (3)TDMA (IS-136) handsets, and offers an integrated solution of LNA with adjustable IIP3. The IIP3 can be fixed to a desired current level for the receiver's linearity requirements.

Features of the MGA725M4 are:(1)operating frequency: 0.1 GHz to 6.0 GHz;(2)noise figure: 1.2 dB at 800 MHz and 1.4 dB at 1900 MHz;(3)Gain: 17.5 dB at 800 MHz and 15.7 dB at 1900 MHz;(4)bypass switch on chip Loss=typ 1.6 dB (Id < 5 A) and IIP3=+10 dBm;(5)adjustable input IP3: +2 to +14.7 dBm;(6)miniature package: 1.4 mm x 1.2 mm and 2.7 V to 5.0 V operation.

The absolute maximum ratings of the MGA725M4 can be summarized as:(1)maximum input to output voltage: 5.5 V;(2)maximum input to ground DC voltage: +0.3 to -5.5 V;(3)supply current: 70 mA;(4)power dissipation: 300 mW;(5)CW RF input power: +20 dBm;(6)junction temperature: 170;(7)storage tempera-ture: -65 to +150.
