  • Combined coaxial connector and radio frequency switch assembly
    Patent number: 5278570
    Abstract: An antenna connector and RF switch assembly (10) is provided on a portable radio (14). The radio includes a self-contained antenna (16) and a radio circuit (27). The assembly (10) is used for selectively connecting the radio circuit (27) to the antenna (16) or to an external signal supply (39). In the assembly, a switchable conductive center contact portion (22, 20, 35) selectively engages either the antenna (16) or the external signal supply (39). A metallic housing (18), having an antenna bushing (17), receives the antenna (16). A molded dielectric insulator portion (26) separates the switchable conductive center contact portion from the metallic housing and is directly connected to the antenna bushing.
