General exam question G6B12
Subelement G6, CIRCUIT COMPONENTS· Group G6B
Which of these connector types is commonly used for low frequency or dc signal connections to a transceiver?
- A.PL-259
- B.BNC
- C.RCA Phono (correct answer)
- D.Type N
WhyRCA phono connectors are commonly used for low frequency or DC signal connections to a transceiver. RCA phono connectors are simple, unshielded (or lightly shielded) connectors well suited to low-frequency audio or DC connections on a transceiver, such as accessory or keying jacks, answer C. PL-259, BNC, and type N connectors are all built for RF signal paths and impedance-controlled performance, overkill and less convenient for simple low-frequency or DC connections.
