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.
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.
