Clean Signals from DC to 3GHz
You need a low pass filter that doesn't compromise your fundamental band. This DC~3GHz Low Pass Filter maintains ≤1.0dB insertion loss across the entire passband, so your signals stay strong. VSWR is ≤1.6:1, meaning reflections won't trouble your transmitter or receiver. Whether you're filtering harmonics from an amplifier or cleaning up a test setup, this DC~3GHz Low Pass Filter delivers predictable, repeatable performance.
Deep Attenuation Where It Counts
Harmonics and spurs starting at 4.5GHz? Gone. The DC~3GHz Low Pass Filter provides ≥50dB attenuation from 4500MHz all the way to 8000MHz. That's the kind of sharp roll‑off that keeps your higher bands clean and your system compliant. The DC~3GHz Low Pass Filter is rated at 100W continuous power, uses 50Ω impedance, and comes with industry‑standard N‑Female connectors. The aluminum housing with silver surface treatment ensures durability and reliable grounding.
