Discrete to Highly Integrated Solutions
Discrete
MMIC
MCM
Skyworks Solutions is uniquely qualified to provide the level of integration that matches the needs of our customers’
design goals. Our broad portfolio includes solutions from discrete diode and transistor devices to Microwave Monolithic
Integrated Circuit (MMIC) designs. Using these discrete and MMICs, we are able to offer Multichip Module (MCM) products
fully encapsulated on a laminate substrate. These MCMs contain all necessary bias and matching circuits to offer a drop-in
component count for integrated solutions. MCMs are offered for many wireless infrastructure applications in amplifiers,
mixers and modulation/demodulation.
