5900

Netcom’s 5900 is a digitally tunable filter covering the frequency range of 225 to 450MHz.

The filter design is based on cavity resonators and includes an integrated digital control interface. With its unique design, it offers a high-power and low insertion loss performance in a small package. It has been designed specifically for higher order modulation systems and data applications having a constant 14MHz filter bandwidth over the entire frequency range. The digital control interference is provided to accept either parallel data and strobe or serial data, clock and strobe.

Options are available upon request for different bandwidth, insertion loss and frequency range.
