The LLC34-35-FF is a bidirectional airline coupler with 3.5mm female input and output ports, designed for high-power applications such as amplifier monitoring and load pull testing. It operates from 2.0 to 34.0 GHz with a maximum insertion loss of 0.35 dB, a typical directivity of 14 dB from 2.0 to 26.5 GHz and 10 dB from 26.5 to 34.0 GHz, and a power handling rating of 150 W CW and 500 W peak. The coupler exhibits excellent VSWR and broadband performance, with no added dielectric to minimize loss and thermal drift. Its construction supports integration in high-power base stations and test systems where calibration stability and minimal signal attenuation are critical.
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.
