Product Description
Product Overview
The BFCN-1945+ is an LTCC Band Pass Filter constructed with 12 layers, offering miniature size and high repeatability of performance. It covers the frequency range of 1945 MHz 95 MHz, providing low insertion loss and good rejection. Wrap-around terminations minimize performance variations due to parasitics.
Product Features
- Small Size (3.20mm x 1.6 mm) for high layout density and minimized parasitics.
- Rejection peaks at harmonic frequencies for improved system performance.
- Wrap-around termination for excellent solderability and easy visual inspection.
- LTCC construction provides a rugged package suitable for tough environments.
