features 24 db gain typical f20 mesfet technology 21dbm output power typ @6v high & low gain states pae (max) 25% description the P35-4720-000-200 is a high performance gallium arsenide driver amplifier mmic. it is primarily intended for wireless applications in the 5-6 ghz bandwidth such as u-nii (unlicensed national information infrastructure) and hiperlan (high performance local area network). the three-stage amplifier requires plus and minus 5v power supplies. also incorporated into the design is the ability to switch between two gain states, high and low gain, as well as a chip standby mode which typically draws 0.1ma. in addition the design has been optimised for the effects of a single bondwire at both the input and output. the die is fabricated using moc?s f20 gallium arsenide mesfet mmic process and is fully protected using silicon nitride passivation for excellent performance and reliability. electrical performance ambient temperature = 223 c, z o = 50 w , vgg = -5v, vdd = +5v notes 1 high gain state 2 all parameters measured on wafer gaas mmic driver amplifier, 5-6ghz P35-4720-000-200 marconi optical components parameter conditions min typ max units small signal gain 1,2 5ghz - 6ghz 22 24 - db gain flatness1,2 5ghz - 6ghz - 1.0 - db input return loss1,2 5ghz - 6ghz 10 20 - db output return loss1,2 5ghz - 6ghz 8 12 - db noise figure1,2 5ghz - 6ghz - 4.5 - db p-1db output power1,2 5ghz - 6ghz - 19 - dbm toi1,2 5.5ghz - 29 - dbm supply current (idd) 2 disabled - 0.1 1 ma supply current (idd) 1,2 enabled (no rf) - 118 ma
