Product Description
Product Overview
Mini-Circuits BFCN-2850+ LTCC Band Pass Filter is designed for harmonic rejection, transmitters/receivers, and WiMAX applications. Constructed with multiple LTCC layers, it offers miniature size, high repeatability, and wrap-around terminations to minimize parasitic variations. This filter provides low insertion loss and good rejection across its 200 MHz passband.
Key Features
- Small Size, 1206: Allows for high layout density and minimizes parasitic effects.
- Wrap-around termination: Provides excellent solderability and easy visual inspection.
- LTCC construction: Offers a rugged package suitable for harsh environments (high humidity, high temperature).
- Rugged Power handling: Capable of handling up to 1.5 Watts in a small package.
- Good Rejection: 25 dB Typ.
- 1206 Surface Mount Footprint
- Power Handling: 1.5 Watts
Applications
- Harmonic Rejection
- Transmitters / Receivers
- WiMAX
