The LLC18-N-FF is a bidirectional coaxial coupler with Type N female input and output ports, designed for high-power applications including amplifier monitoring and load pull. It operates from 0.6 to 18.0 GHz with a maximum insertion loss of 0.25 dB up to 8.0 GHz and 0.25 dB from 8.0 to 18.0 GHz, and a typical directivity of 15 dB up to 8.0 GHz and 10 dB from 8.0 to 18.0 GHz. The coupler handles 500 W continuous wave and 2 kW peak power, features low insertion loss with no added dielectric, and maintains excellent VSWR and broadband performance. Its construction uses precision-machined airline technology to ensure consistent performance under high-power conditions without measurable degradation.
The LLC-series of bidirectional airline couplers represents a breakthrough in high-power coupler technology. Combining precision machining with stellar electrical characteristics, LLC-series couplers offer unmatched performance offering high directivity and low insertion loss for broadband performance.
The LLC-series’ high directivity is important as poor directivity can invalidate calibration and result in erroneous measurements. Its low insertion loss is critical for high-power applications in order to avoid power loss and eliminate drift due to heating. When used as part of a vector-receiver load pull setup this directly maximizes tuning range when combined with an impedance tuner.
