BTBPF for Up-Converters - Broadband Terminated BPF

Product

Typically in up-conversion applications, matching is accomplished by placing an attenuator pad between the mixer and filter, followed later by re-amplification of the RF signal. K&L’s BTBPF eliminates the need to attenuate then re-amplify.
