Netcom’s 5587 is a digitally tunable filter covering the frequency range of 90 to 520MHz.

The filter has been designed using two bands of tunable filters from Netcom’s proven 5500 Series. This dual-band filter is offered in a smaller integrated SMT package to support applications where compact design and board layout flexibility is important.

It uses new commercially available high voltage drivers and a new generation CPLD, which allows for improved performance and reduced cost while at the same time providing increased functionality. The 90-520MHz filter incorporates high voltage totem pole drivers for the PIN diode bias voltage to minimize current draw from the 100 VDC supply.
