AFS14 Evaluation boards are designed to provide a means to assess the performance of AFS14 series of SAW

Band Pass Filters. The board is designed with a provision for matching components on both input and output

ports of the filter.

To complete the electrical path, resistors R1 & R2 are in-circuit with 0Ω value. The land pattern for C1 C2,

C3 & C4, along with the land pattern for R1 & R2 can be used to create a matching circuit using a combination

of inductors and capacitors as desired.

By default, the AFS14 series of SAW Band Pass Filters are designed into a matched impedance of 50Ω’s, so

these evaluation boards can be used as received. Simply solder down the AFS14 series of filter on the

provided land pattern, and connect the Input and Output ports, using SMA to BNC or SMA to N-Type

connectors to a Network Analyzer.
