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

and adjacent circuit the same height. The amount of
epoxyusedforthechipand/orshimattachmentshould
bejustenoughtoprovideathinfilletaroundthebottom
perimeterofthechiporshim.Thegroundplainshould
befreeofanyresiduethatmayjeopardizeelectricalor
mechanicalattachment.
The location of the RF bond pads is shown in Figure
12.NotethatalltheRFinputandoutputportsareina
Ground-Signal-Groundconfiguration.

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.

Biasing and Operation
The recommended quiescent DC bias condition for
optimumefficiency,performance,andreliabilityisVd=5.5
voltswithVgsetforId=800mA.Minorimprovementsin
performancearepossibledependingontheapplication.
Thedrainbiasvoltagerangeis3to5.5V.AsingleDCgate
supplyconnectedtoVgwillbiasallgainstages.Muting
can be accomplished by setting Vg to the pinch-off
voltageVp(-1.0V).
An optional output power detector network is also
provided.ThedifferentialvoltagebetweentheDet-Ref
