Knowles B140MB4S Surface-Mount Bandpass Filter
Knowles B140MB4S Surface-Mount Bandpass Filter (BPF) is designed to cover the Satellite Communication (SATCOM) band centered at 14.0GHz. This bandpass filter is small in size and uses low-loss, temperature-stable materials to minimize performance variation with temperature. The B140MB4S fully shielded component features frequency stability over temperature and operates over the -55°C to +125°C temperature range. This BDF is a shielded construction for space-constrained RF and microwave designs. The B140MB4S BDF is ideal for SATCOM terminals, transceivers, RF and microwave communication systems, aerospace and defense communication equipment, frequency separation, and signal routing networks.
