Filters Fit Lowpass And Bandpass Needs

May 22, 2014
Lines of lowpass and bandpass filters are suitable for processing analog signals from 10 to 1700 MHz.

New lowpass filters (LPFs) and bandpass filters (BPFs) based on lumped-element inductive-capacitive (LC) technology have been developed for operating frequencies from 10 to 1700 MHz. As an example of the BPF products, model AE1075B11144 is a surface-mount-technology (SMT) filter measuring just 47 × 15 × 7 mm with a center frequency of 1075 MHz and bandwidth of 1050 MHz. It achieves 20-dB attenuation out of band at 490 MHz and 40 dB minimum attenuation at 1800 MHz. The passband insertion loss is 3 dB or less with minimum return loss of 13 dB. As an example of the LPF products, model AE1600L9159 is also an SMT filter measuring just 13 × 12 × 5.3 mm with a bandwidth of 1370 to 1600 MHz and only 2 dB maximum insertion loss. The rejection at 3088 MHz is at least 25 dB. These filters handle operating temperatures from -45 to +85°C.
