📦 Types of Ceramic Filters:
🔹 RF Ceramic Low Pass Filter (LPF)
Blocks high-frequency signals while allowing lower frequencies to pass. Ideal for harmonic suppression and EMI reduction in compact RF systems.
🔹 RF Ceramic High Pass Filter (HPF)
Allows high-frequency signals to pass while attenuating lower frequencies. Commonly used for blocking interference and low-frequency noise.
🔹 RF Ceramic Band Pass Filter (BPF)
Passes only a specific frequency band and attenuates signals outside that range. Used for channel selection in wireless receivers and transmitters.
🔹 RF Ceramic Duplexer
Combines two filters (typically a transmit and receive bandpass) into one component to allow simultaneous transmission and reception on a single antenna. Essential in compact, full-duplex RF systems.
