This multicoupler is made up of four coaxial cavity resonators coupled on a single antenna port. Each input port can accept up to 200W (no extra fan requested).
A capacitor network at the open end of the cavity center conductor performs tuning. Capacitors are switched by PIN diodes to allow high tuning speed.
A microprocessor controls PIN diode drivers and gives information on diode status (On/Off, temperature, etc). An isolator protects each port. All breakdowns are automatically detected.
