The LLC67-185-FF is a bidirectional airline coupler with 1.85mm female connectors, designed for high-power applications such as load pull and amplifier monitoring. It operates from 3.0 to 67.0 GHz with a maximum insertion loss of 0.4 dB at 67.0 GHz, a coupling factor of 45 ±5 dB, and a directivity of 35 ±5 dB. The coupler handles 10 W CW and 100 W peak power. It features low insertion loss, high directivity, and broadband performance, with no added dielectric to prevent self-heating. The connector type and performance characteristics are specific to this variant within the LLC-series.
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.
