The Kaben KR-SIF-LP-233-02 filter is the industry's first on-chip analog filter for W-USB application. This receiver cell is a key building block for wide bandwidth and no phase dispersion, such as for W-USB.
Kaben's unique filter offers a passband frequency of DC to 233 MHz. The FIR filter gives linear phase and no group delay distortion. The gain can be varied between 30 and 44 dB in 2 dB steps to accommodate a wide range of input signal levels.
The sharp transition bandwidth allows sampling at the minimum rate of 528 Msps without additional digital filtering.
Unlike a traditional digital FIR filter, the KR-SIF-LP- 233-02 provides sin x/x attenuation (approximately 20 dB) of any signal located at the aliased
sidebands about the sampling clock frequency. The Anti-Alias filter also allows for out-of-band signals to be larger than the 60 dB dynamic range.
