CustomRF is a consulting and engineering services company focusing on the design, analysis, modeling and trouble-shooting of radio-frequency (RF), microwave and wireless systems and circuits. Our expertise includes mobile phones, WiFi, satellite communications, backhaul radios and RFID. We specialize in 3-dimensional electro-magnetic field (3D EMF) simulation in CST Microwave Studio, which lends itself well to solving problems related to antenna (near and far-field), EMI/EMC and device packages, especially when things are very small and difficult to probe. If you need a consultant to review your design, or to provide advice during the design phase, call us. Located in the Boston, Massachusetts area, CustomRF markets its services world-wide. We speak German and French and have extensive international experience (Europe, Africa, Asia).
