The Avair AV-38D is a commercial-grade, high-isolation radio frequency (RF) triplexer engineered to multiplex three disparate transceiver or receiver outputs into a single shared antenna transmission line infrastructure. Utilizing a sophisticated network of high-Q passive filters—including Low Pass (LPF), Band Pass (BPF), and High Pass (HPF) architectures—this heavy-duty unit routes HF/VHF, UHF, and SHF spectrums simultaneously without mutual cross-talk or impedance mismatches. It stands as an essential physical utility asset for base station engineers, complex communication repeater sites, maritime vessel installations, and high-rotation B2B electronics distribution networks.
Built to sustain continuous high-power transmission and active workshop deployment, the internal filter matrix is enclosed within a rugged, low-profile metallic chassis measuring 85 x 27 x 64 mm and weighing 300 grams. The RF distribution layout features a premium 50-Ohm calibration offering excellent Voltage Standing Wave Ratio (VSWR < 1.2:1) and ultra-low insertion loss across all ports. The physical hardware interface is designed with a heavy-duty N-Female primary input bulkhead, transitioning into an M-Type (PL-259) connector for the HF/VHF line, and dual precision N-Type connectors for the dedicated UHF and higher microwave spectrum legs to maintain maximum shielding and minimal signal attenuation.
