Wi-Fi Cavity Bandpass Filter Provides Reliable Outdoor Performance

For suppressing interference and improving the performance of IEEE 802.1a/b/n access points in outdoor environments, the Model AB2436B479 eight-cavity bandpass filter has a center frequency of 2,436.5 MHz, -3 dB bandwidth of 70 MHz, typical insertion loss of 0.9 dB at center frequency, typical return loss of 18 dB, and a typical harmonic rejection of 90 dB. Selectivity at center frequency ranges from less than 91 MHz at a 20 dB bandwidth to less than 150 MHz at a 60 dB bandwidth. The filter handles an RF input power of 50W, has an operating temperature of -40?C to +85?C, measures 4.84” x 2.8” x 1.22”, and has Type-N female RF connectors. Additionally, standard configuration and specs of the Model AB2436B479 are customizable to meet specific requirements. ANATECH ELECTRONICS INC., Garfield, NJ. (201) 772-4242.
