RFMW, Ltd. announces design and sales support for the SKYA21001, AEC-Q100 qualified SPDT switch. The SKYA21001 from Skyworks Solutions was developed for in-vehicle telematics and infotainment applications. However, defense/aerospace companies have adopted the switch as a low cost alternative to semi-custom and upgraded products. Covering a frequency range of 20MHz to 3GHz, the SKYA21001 is ideal for military communication systems. Low insertion loss of 0.3dB improves system performance while low DC power consumption helps maintain battery life in portable systems. Offered in a compact, 2.0 x 1.25mm SC-70 package, this Skyworks is lead-free and RoHS compliant.
RFMW, Ltd. announces design and sales support for a series of voltage-controlled variable attenuators (VVAs) from Skyworks Solutions. The SKY1223x series of attenuators is suitable for applications such as repeaters, wireless backhaul and wireless infrastructure. The four attenuators in the series, SKY12232-21, SKY12233-11, SKY12235-11 and SKY12236-11, are optimized for low distortion and centered at 1.95, 2.60, 3.15 and 3.8GHz respectively. Together, the attenuators cover operation from 1.45 to 5.0GHz and have control voltages ranging from 0-5V. Typical insertion loss of ~1.5dB offers improved system efficiency and attenuation >25dB provides excellent receiver protection. All four attenuators are packaged as 4.9×3.2x1mm multi-chip…
RFMW, Ltd. announces design and sales support for a high linearity, active bias, ultra low noise amplifier from Skyworks Solutions.
