RFMW, Ltd. announces availability of a white paper from Dielectric Laboratories (DLI). “Choosing blocking capacitors – it’s more than just values” outlines how designers often use rules-of-thumb or approximate equations linking capacitor values to final RF performance. DLI takes a real world look at performance that can’t be predicted by design theory, and then analyzes common capacitor bypass networks to compare actual measurements against theoretical performance.
RFMW, Ltd. announces design and sales support for thin film, fixed attenuator pads from SemiGen, Inc. SemiGen offers a series of fixed attenuators from 1 to 30dB in 1dB increments with flat frequency response from DC to 50GHz. The SFAP series feature precise resistor films and superior metallization resulting in consistent performance and reliability. Full side wraps connect the topside ground to the backside metallization for surface mount or on-board installation. Gold bondable top side contacts for the input and output make these ideal for standard RF/microwave assembly techniques. Power handling is 1 to 5 Watts CW. Return loss is…
