This high-precision RF attenuator covers a frequency range from DC to 4000MHz and offers attenuation values of 3, 6, 10, 15, 20, 30, and 40 dB. It features a 50Ω impedance and maintains a low VSWR of ≤1.21, ensuring efficient signal transmission with minimal reflection. The in-band ripple is exceptionally low, ranging from ≤0.3 dB to ≤1.2 dB depending on the attenuation level. The attenuator provides excellent PIM performance, with PIM3 ≤-105 dBc @ 2X43dBm and PIM5 ≤-120 dBc @ 2X43dBm, making it suitable for high-interference environments. It is equipped with 4.3-10 male to female connectors and operates reliably within a temperature range of -20°C to +55°C. Ideal for demanding RF applications requiring precise attenuation and high signal integrity.
