VDI
VDI offers a broad range of millimeter-wave varactor and varistor-mode frequency multipliers based on planar GaAs Schottky diode technology. No tuners are used and many devices offer broadband performance without bias. See the table below for a partial listing of our current line of components. Click on the model number for more information. Models starting with "WR" give full waveguide band operation and "D" denotes high-power frequency doublers having approximately 10% 3dB bandwidth.
Multiplier Chains (MC) and Amplifier Multiplier Chains (AMC) are available using a variety of multiplier combinations to achieve Customer specifications. VDI also offers additional multipliers not listed below. Complete Transmit and Receive Systems are available to achieve Customer specifications; see Systems; contact VDI today for additional information and discussion of specifications.
