Polyphase microwave
WebIn general, there are L polyphase filters. Having the designed interpolation filter H ( z) of N taps, we can determine each bank of filter coefficients as follows: (11.12) For our example, L = 2 and N = 4, we have L − 1 = 1, and N / L − 1 = 1, respectively. Hence, there are two filter banks, ρ0 ( z) and ρ1 ( z ), each having a length of 2 ... WebWhile polyphase filters produce a wideband phase shift, the amplitude mismatch between the I and Q components is poor for wide bandwidth. The bandwidth can be enhanced by using inductors in the polyphase network as demonstrated [5], [10]. The main ad-vantage of the polyphase filter over a microwave I/Q generator
