Lumped Bandpass Filters
Sirius Microwave's series of lumped element filters covers passband frequencies from few KHz to 5GHz, while stopbands extend to 18GHz. These filters are available for bandwidths from 1% to multi-octave. Lumped element filters can be optimized for low loss, high power, compact size and high selectivity. Some examples of lumped element designs are listed in table below. Contact factory for details here.
Features:
Chebyshev, Elliptic or Linear Phase
Symmetric or Non-symmetric Rejection
