K&L offers 6- to 18-GHz surface-mount high-pass filters

April 21, 2017

Salisbury, MD. K&L Microwave announced it has developed a family of miniature high-pass filters with cutoff frequencies of 6 to 18 GHz. The filters guarantee rejection of 45 dB at 1/2 the 3-dB cutoff frequency and insertion loss of 2.5 dB max. The surface-mount package measures 0.44 inches long by 0.24 inches wide by 0.16 inches high.

Each unit in the seven-section AH Series high-pass filters provides Chebyshev response realized via a thin-film on alumina substrate, typically 0.025” thick, using a sputtering process that guarantees enhanced Q and high repeatability. Filters can be soldered to a PWB with recommended permittivity range of 3 to 4 or adhered to metal carrier with silver epoxy.

The filters are designed in a shielded open-frame style, and the vendor advises placement in a channelized groove to minimize RF leakage and coupling paths between input and output ports.
