This high-performance RF attenuator features a frequency range from DC to 4000MHz and offers various attenuation levels (3/6/10/15/20/30/40 dB) to meet diverse signal processing needs. With an impedance of 50Ω and a VSWR of ≤1.21, it ensures minimal signal reflection and high-quality performance. The in-band ripple is exceptionally low, ranging from ≤0.3 dB to ≤1.2 dB depending on the attenuation level. The attenuator exhibits excellent PIM performance, with PIM3 ≤-120 dBc @ 2X33dBm and PIM5 ≤-145 dBc @ 2X33dBm. It is equipped with 4.3-10 male to female connectors and operates reliably within a temperature range of -20°C to +55°C. This attenuator is ideal for high-frequency applications requiring precise signal attenuation and minimal interference.
