The MACOM H-9 Hybrid Junction is a passive 180° hybrid coupler engineered for signal division and combination across 2 MHz to 2 GHz. This connectorized component delivers 10-octave bandwidth with 50 Ω nominal impedance, minimum 30 dB isolation, and 3 dB nominal coupling. Frequency-dependent insertion loss ranges from 0.7 dB to 2.5 dB maximum, while amplitude balance holds ±0.5 dB across the full band. Phase balance performance spans 2° to 7° depending on frequency segment. VSWR varies from 1.4:1 at mid-band to 3.5:1 at the low frequency extreme. Input power handling reaches 25 W across 20–2000 MHz and 5 W at 2–20 MHz. Operating temperature range is −55°C to +85°C.
