The LNA has low noisefigureandhighgainachievedthroughtheuseof Avago Technologies’ proprietary GaAs Enhancement- modePHEMTprocess.Itishousedinaminiature2.0x 2.0x0.75mm8-pinLeadless-Plastic-Chip-Carrier(LPCC) package.Thecompactfootprintandlowprofilecoupled withlownoise,highgainandhighlinearitymakesthe MGA-665P8 an ideal choice as an LNA for broadband general-purpose applications. Its excellent broadband isolationalsomakesitagoodbufferamplifier. The output of the MGA-665P8 provides a very good broadband match to 50Ω. Its input requires a simple external LC network to provide a low noise figure and goodinputreturnloss.Powersupplyvoltageisapplied toboththeoutputterminalandaseparateVDterminal. A simple external bias insertion circuit consisting of a shunt inductor and a series dc block capacitor is suf- ficient to apply power supply voltage to the output of theMGA-665P8.TheMGA-665P8providestypicaldevice performanceof 1.45dBnoisefigure,16dBgainandan OIP3of+18.1dBmat5.25GHz,atabiaspointof3Vand 20.5mA.
