Product Overview
The LFCN-123+ Low Pass Filter offers microwave communication system designers the ability to reject unwanted harmonics with defined RF parameters. Its multilayer LTCC construction ensures high repeatability of performance, while small wrap-around terminations minimize parasitic variations. Covering DC-12000 MHz, these filters provide low insertion loss and good rejection.

Notes:
1. In Application where DC voltage is present at either input or output ports, coupling capacitors are required.
2. Measured on Mini-Circuits Characterization Test Board TB-860+.
3. Passband rating, derate linearly to 3W at 100C ambient. Permanent damage may occur if any of these limits are exceeded.
