The 5555 from Netcom is a Tri-band Tunable Filter that operates from 1.5 to 30 MHz. It has been designed using three bands of tunable filters with passbands from 1.5 – 4 MHz, 4 – 10 MHz, and 10 – 30 MHz. The filter has an insertion loss of less than 4.5 dB and a tuning speed of less than 200 μs. It can handle an input power of up to 30 dBm (in-band) and 33 dBm (out of band). The filter requires a DC supply from 4.5 to 5.5 V and consumes less than 260 mA of current. It is available in an SMT package that measures 55.9 x 55.9 x 12.7 mm and can be controlled via an SPI interface. The filter meets the vibration and shock requirements of systems used in ground-mobile and airborne environments.
