SemiGen has announced that a series of microwave chip capacitors are now available. Series 8000 capacitors offer a working voltage of >50V and capacitance ranges from 2.0 pF to 600 pF. Series 8100 capacitors offer a working voltage of >100V and capacitance ranges from 0.1 pF to 399 pF. They are made with prime starting material and consist of an Oxide/Nitride layer that provides low dielectric loss and high standoff voltage. They feature very high Q, low temperature coefficients, low dissipation factors, and long term stability. Gold contacts are provided on front and back, and die thinness of as little as 3 mils is achievable for limiting inductance. Uses for these high performance microwave capacitors include applications that require DC protection, RF bypassing or fixed tuning, such as in RF amplifiers, oscillators, switches, filters and multipliers.
These products are available in chip form only.
