Description
Skyworks’ four-stage, reactively-matched GaAs MMIC
amplifier has a typical small signal gain of 28 dB with a
typical noise figure of 2.5 dB with P1 dB > 14 dBm at
26 GHz. The device is ideal for Ka band SatCom and point
to multi-point applications. The FETs employ surface
passivation to ensure a rugged, reliable part with
through-substrate via holes and gold-based backside
metallization to facilitate a conductive epoxy or solder die
attach process. The RF interface has been designed for
high volume automatic bonding assembly, allowing for
(2) 1.0 mil Au wire. All chips are screened for
S-parameters, output power and noise figure prior to
shipment for guaranteed performance.
