Coaxial Bandpass Filter

Coaxial Bandpass Filter

Huasen Microwave's Coaxial Bandpass Filters (CBPF): Coaxial cavity structure microwave devices, used to select specific frequency bands and suppress out-of-band interference. They feature high Q value, low loss, and compact size, with a frequency range of DC-60 GHz.
- High Q value and low loss (IL ≤0.8 dB) to improve efficiency
- Compact size
- Wide frequency coverage
- High out-of-band suppression ≥60 dB)
- Made from aluminum or copper, with silver-plated or oxidized surfaces.
