Supplier Storefronts for Application: GaAs - Gallium Arsenide

Access the latest products and information from our suppliers

Gallium arsenide (GaAs) is a mature, proven RF semiconductor process that offers high frequency performance at low cost. GaAs is useful to 90+ GHz and can provide noise figures in P-, L- and S-band of 0.35 dB or lower – all at low cost. GaAs also remains the most economical option for power amplifiers in the 1 to 90 GHz range. Cellular infrastructure, CATV, A&D, and ISM are all applications that have greatly benefited from the price/performance advantages that GaAs provides.

Richardson RFPD has an extensive GaAs offering, including the latest products and design resources focused exclusively on this proven technology. With more than a decade of design experience with GaAs amplifiers, switches, and other GaAs components, we can recommend the product to meet your design needs. Browse our selection of the newest products from industry leading manufacturers ANADIGICS, Analog Devices, NXP, MACOM, Skyworks, Qorvo, and UMS.
