Broadband Conical Inductors
AEC• Designed specifically for broadband and high frequency
applications.
• Operates as a series of narrow-band inductors throughout
an operating frequency range of 10 MHz up to 40 GHz.
• Ideal for use in ultra-wideband bias Tees, where the conicalinductor provides the path for the DC bias injection or extraction
while isolating the power source from the active device.
• Supplied with “flying leads” that allow adjustment of themounting angle.
• For a surface mount version with a self positioning mounting
bracket, consider the BCR series.
