RF Filter

Lowpass / Bandpass / Highpass Filter

Corech Microwav’s RF Filers frequency ranges from dc to 67 GHz, band pass/high pass/low pass designs, narrow-band/wide-band types to meet customers various needs. These low pass filters(LPF), high pass filters (HPF), and band pass filters (BPF) offer very low insertion loss, outstanding VSWR and long-term performance.

Corech’s RF Filters are available in PIN, 1.85mm, 2.4mm, 2.92mm, N, SMA, BNC, and waveguide connectors. They are crucial to manage signal integrity, reduce interference, and ensure efficient communication. Met RoHs, REACH and GJB 9001 standards. We are also capable to custom designs to meet customers’ specific needs.
