API Technologies’ configurable switched filter banks (310-020050-XXX series) offer customer-defined passband
frequencies from 20 MHz to 7500 MHz with 2-7 channels. This series features the same high performance of a
custom designed switched filter at a reduced cost. This cost reduction is achieved by using common switch manifolds
and machined parts that are populated with custom filters. The filter banks are ideal for a wide range of applications
were low cost and high performance is required.
