AWD1900

The AWD1900 is a monolithic drive amplifier suited for PCS telephone applications.

There are some features AWD1900 as follows.First is high linearity.The second is built in step attenuator.Then is high gain.Next is 28 Pin SSOP plastic package.The fifth is switchable RF output.The sixth is low cost.The last one is single supply.

What comes next is about the AWD1900 electrical characteristics (f=1850 to 1910 MHz,V_DS1=V_DS2=V_DS3=+5 VDC,V_REF=+3.6 V_CC,TC=25,50 system).The minimum fo (frequency) is 1850 MHz and the maximum is 1910 MHz.The maximum high power output is 10.5 dBm and the maximum low power output is -3.5 dBm.The typical high gain is 32.5 dBm and the typical low gain is 18.5 dBm.The typical quiescent current is 100 mA.The typical input return loss is 15 dB.The typical high mode noise figure is 2.7 dB and the typical low mode noise figure is 8 dB.The typical attenuator is 14 dB.The typical isolation (RF_OUT1 to RF_OUT2) is 15 dB.
