BJ260(WR34) Waveguide Filter
Filters & MultiplexersKa-band

Overview
The BJ260(WR34) Waveguide Filter (JL.2.832.0017) is a Ka-band microwave passive device based on a metallic waveguide resonant cavity structure. It is designed for frequency selection, allowing the 26.4 GHz center frequency to pass with minimal loss while providing high rejection in the stopband. The ±25 MHz 1 dB bandwidth, combined with out-of-band rejection of ≥25 dB at ±60 MHz, ≥35 dB at ±90 MHz, and ≥60 dB at ±200 MHz offset, make it ideal for satellite, radar, and communication applications. The compact aluminum alloy housing (50 × 30.7 × 21.1 mm) with white paint finish operates over −45 °C to +85 °C.
