The LLC90WR12 is a waveguide coupler with an integrated downconverter for 60-90 GHz applications, designed for load pull and high-power mmWave testing. It features a 3.5mm female input and output port, 0.8 dB maximum insertion loss at Fmax, 30 dB typical directivity, and 435 dB coupling, with a power handling rating of 5 W CW. The integrated X6 downconverter enables direct connection to sub-26.5 GHz VNA receiver ports. It uses WR12 waveguide and requires an external local oscillator (max 2 dBm).
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.
