二、RF Isolator：Overview，Appearance and Characteristics

1. RF Isolator, also known as "One-Way Isolator", "circulator", is a device that transmits RF signals in one direction.

2. When the RF signal is transmitted in the forward direction, the RF signal at the input end (IN) can be transmitted to the load connected at the output end (OUT) with very low loss. For the reflected signal from the load end, it will be fully absorbed by the dummy load connected at the isolation end (ISO).

3. The unidirectional transmission characteristics of RF signal isolator can be used to isolate the impact of load changes on the input signal source.

4. Characteristics:

（1）Input Power: ≤50W.

（2）Forward Transmission Loss: ≤-1dB (transmission loss between input IN and output OUT).

（3）Isolation: ≥ -20dB (isolation between output OUT and input IN).

（4）Impedance: 50Ω.

（5）Connector: N-type female.

（6）VSWR: ≤ 1.2.

（7）Dummy load: 50W, 0-3GHz，50Ω.

三、RF Relay：Overview，Appearance and Characteristics

1. RF relay, in the airport air traffic control equipment, is mainly used for the main and standby switching of two RF signals.

2. The two RF input signals of the relay are switched by the relay, one is connected to the transmitting antenna system, and the other is connected to the dummy load system,

3. RF relay can be divided into single pole (two in and one out) and double pole (two in and two out).
