Frequently Asked Questions
-
Q1: What is the primary function of a 2x2 hybrid coupler?
A: A 2x2 hybrid coupler is used to combine two independent VHF signal sources and evenly distribute signals to two output ports, widely applied for indoor private radio communication systems to reduce signal crosstalk.
Q2: Why is port isolation ≥24dB important for this coupler?A: High port isolation over 24dB effectively isolates signals between different ports, preventing mutual interference of signal sources and guaranteeing stable signal transmission in the whole communication system.
Q3: What are the advantages of N-Female connectors for this model?A: N-Female connectors have stable electrical performance within 68-72MHz VHF band, low VSWR and good power bearing capacity, matching most conventional radio equipment interfaces for easy installation and connection.
Q4: Can this hybrid coupler work under continuous high-power input?A: Yes, it supports 50W average power handling, which can stably bear long-term power input from VHF radio base stations without performance attenuation.
