Kaben Wireless Silicon

Kaben has developed the industry's most flexible field programmable analog filter. This on-chip filter is a key building block in the design of multi-mode wireless systems that require the ability to switch between multiple standards.

The novel architecture of the filter features digitally programmable tap coefficients, which provide flexibility in the following parameters: Frequency, Bandwidth, Passband Ripple, Selectivity, Transition Bandwidth, and Stopband Attenuation.

Along with the expected channel select filtering, the architecture provides image reject filtering, anti-aliasing filtering, AGC, sampling, and digitization.

Kaben's unique Programmable Filter offers a center frequency from 70 to 200 MHz with up to 60 MHz bandwidth. The gain can be varied between 0 and 30 dB in 2 dB steps to accommodate a wide range of input signal levels. The FIR filter gives linear phase and no group delay distortion.

The spurious free dynamic range of 60 dB makes this product an ideal choice for wideband applications that require high selectivity and programmability.

The filter can be designed to have high RF image rejection for low IF receivers without the use of digital correction techniques. In multi-mode radios this technique can eliminate one or more off-chip IF filters. The Anti-Alias filter also allows for out-of-band signals to be larger than the 60 dB dynamic range.
