They are continuously adjustable (using a thumb wheel or a screw head for examples), and consume zero DC power. They are passive, reciprocal networks (either side can serve as input). Our company was established with a mission to improve the lives of Zambian and African people through innovative business solutions and ventures that drive economic growth, create employment opportunities, and promote sustainable development. New for June 2019: mechanically variable attenuators are often used in lab equipment, so that one unit can serve many purposes (instead of a drawer full of fixed attenuators). Availability In-stock and ready to ship same-day with no minimum order. ADIsimRF is an easy-to-use RF signal chain calculator. It calculates Cascaded Gain, Noise Figure, IP3, P1dB and Power Consumption. Stages can be easily inserted, removed or temporarily muted. Analog Devices' RF attenuators are available in. 3,455 RF Variable Attenuators from 100 manufacturers listed on everything RF Variable attenuators provide continuously or step-adjustable loss to set path gain or emulate fading while maintaining good return loss. They are used for AGC loops and test fixtures, specified by range, flatness.
