Biasing and Operation
The recommended quiescent DC bias condition for
optimumefficiency,performance,andreliabilityisVd=5
voltswithVgsetforId=950mA.Minorimprovementsin
performancearepossibledependingontheapplication.
Thedrainbiasvoltagerangeis3to5.5V.AsingleDCgate

can be accomplished by setting Vg and /or Vg to the
pinch-offvoltageVp.
An optional output power detector network is also
provided.ThedifferentialvoltagebetweentheDet-Ref

Assembly Techniques
The backside of the MMIC chip is RF ground. For mi-
crostripapplicationsthechipshouldbeattacheddirectly
tothegroundplane(e.g.circuitcarrierorheatsink)using
electricallyconductiveepoxy[1,2].
Forbestperformance,thetopsideoftheMMICshouldbe
broughtuptothesameheightasthecircuitsurrounding
it.Thiscanbeaccomplishedbymountingagoldplate

epoxyusedforthechipand/orshimattachmentshould
bejustenoughtoprovideathinfilletaroundthebottom

befreeofanyresiduethatmayjeopardizeelectricalor

The location of the RF bond pads is shown in Figure

Ground-Signalconfiguration.
RFconnectionsshouldbekeptasshortasreasonableto
minimizeperformancedegradationduetoundesirable
series inductance. A single bond wire is normally suf-
ficientforsignalconnections,howeverdoublebonding
with 0.7 mil gold wire or use of gold mesh is recom-
mendedforbestperformance,especiallynearthehigh
endofthefrequencyband.
Thermosonic wedge bonding is preferred method for
wire attachment to the bond pads. Gold mesh can be
attached using a 2 mil round tracking tool and a tool
forceofapproximately22gramsandaultrasonicpower
ofroughly55dBforadurationof76+/-8mS.Theguided
wedgeatanuntrasonicpowerlevelof64dBcanbeused
for0.7milwire.Therecommendedwirebondstagetem-
peratureis150+/-2°C.
Caution should be taken to not exceed the Absolute
MaximumRatingforassemblytemperatureandtime.
