3-band suppressor

Purpose: Multi‑band notch (band‑stop) filter that attenuates three selectable frequency bands to remove interference while leaving other bands unaffected.

Typical bands (example): GPS L1 (1575 MHz), Wi‑Fi 2.4 GHz (2400–2483 MHz), and ISM/5.8 GHz (5725–5875 MHz) — customizable per requirement.

Performance: ≥30–60 dB attenuation (depth) in each notched band, with ≤1 dB insertion loss across passbands for minimal impact on desired signals.

Form factor & connectors: Compact RF module (rack mount or in‑line SMA/N‑type connectors), rugged metal housing for field use.

Applications: EMI/EMC testing, protecting sensitive receivers from nearby interference, spectrum pre‑conditioning for measurement rigs, and controlled lab environments.

Compliance & procurement tips: Legal to buy/use for interference mitigation and testing; specify exact center‑freq and bandwidth, ask vendor for attenuation curves (S‑parameters), and request RoHS/CE or test reports where applicable.
