Designed for reduction and removal of unwanted spurious signals, harmonics and sidebands the new AFL Series of coaxial Low Pass Filters from AtlantecRF provide microwave design engineers and technicians with an “off-the-shelf” solution to many spectral purity problems.

As stock items, these suspended substrate filters, which are available with standard cut-off frequencies from 1 to 18 GHz, can be quickly installed in communications equipment according to operating needs and as “select-on-test” components prior to commissioning.

The quasi-elliptical function provides typical insertion loss in the pass-band of 1.2dB with stop band attenuation in excess of 50dB and power handling of 15 watts CW. In a 50ohm system the input and output VSWR is 2.0:1 max.

Sizes range from 100 x 60 mm at the lowest frequency to 24 x 20 mm at the highest and all units have a height of 12mm. Connectors are SMA female to MIL-C-39012, the finish is in matt paint and the operating temperature range is from -55 to +85 C.
