Abstract

An improved portable two-way radio comprises a systems module and a removably connected, shielded RF module. Split universal device connector apparatus is provided having an RF connector portion associated entirely with the shielded RF module and a control connector portion associated entirely with the control module, the RF and control connector portions being located physically proximate to each other so that a single multi-pronged universal device connector can be electrically and mechanically connected to both the RF connector circuitry through the control systems module.

Claims

1. An improved portable two-way radio comprising:

a control systems module;

a shielded RF module removably connected, both electrically and physically, to said control system module and, when so connected together, said RF module and control system module providing an operative two-way radio circuit; and

split universal device contacts having a first part thereof associated with said control systems module and a second part thereof associated with said RF module and including an RF connector, for making external electrical contact with further control and RF circuits respectively.

said first and second parts being located physically proximate to each other on their respective modules such that a single multi-pronged plug associated with said further circuits can be electrically connected to both said first and second parts.

5. The improved radio of claim 1 further comprising means for electrically connecting said control systems module and said RF module.

2. An improved portable two-way radio comprising:

a control systems module having means for controlling a plurality of radio functions;

a control system connector electrically coupled to said controls;

an RF module removably attached to said control systems module, said RF module comprising a transceiver assembly in a shielded metal housing and having associated therewith an RF connector electrically coupled to said transceiver assembly, said RF and control system connectors being located physically adjacent to each other such that a single multi-pronged plug can be electrically connected to both portions; and

means for electrically connecting said control systems module and said RF module.

3. An improved portable two-way radio comprising;

a control systems module housing means for controlling a plurality of radio functions, and having a plurality of externally mounted electrical contacts for remotely controlling said radio functions;

an RF module removably attached to said control systems module, said RF module containing a transceiver assembly in a shielded housing and having associated therewith at least one external RF contact electrically connected to said transceiver assembly, said RF contact being located physically adjacent to said plurality of control systems contacts such that a single multi-pronged plug can be electrically connected to all said contacts; and

means for electrically connecting said control systems module and said RF module.

4. An improved portable two-way radio comprising:

a control systems module including;

a thin-walled front cover defining an interior cavity containing a controller board assembly; and

means electrically connected to said controller board assembly for controlling a plurality of radio functions; and

an RF module removably attached to said control systems module comprising a shielded metal housing containing a transceiver assembly and means electrically connected to said transceiver assembly for conducting RF power into and out of said RF module without passing through said control module;

wherein said controlling means and said RF power conducting means are located physically adjacent to each other on their respective modules such that a single multi-pronged connector plug can be electrically connected to both said controlling means and said RF power conducting means.

6. An improved radio comprising:

a control systems module;

a shielded RF module removably connected to said control systems module; and

split universal device contacts having a first part thereof associated with said control systems module and a second part thereof associated with said RF module,

said first and second parts being located physically proximate to each other on their respective modules such that a single multi-pronged plug can be electrically connected to both said first and second parts;

wherein said RF module comprises

a honeycomb shield disposed within said cavity;

a transceiver board having electronic components mounted on both sides thereof, said transceiver board being sandwiched between said honeycomb shield and said rear cover such that some of said electronic components are at least partially received within said honeycomb grid and said honeycomb shield,

a shield cover closing the otherwise open end of said cavity; and

means connecting said shield cover to said rear cover.

8. The improved radio of claim 6 including:

an antenna; and

an antenna changover switch for normally connecting said transceiver board to said antenna and for alternatively connecting said transceiver board to said first part of said split universal device contacts when said multipronged plug is connected to said radio.

9. The improved radio of claim 6 further comprising means for electrically connecting said control systems module and said RF module.

10. The improved radio of claim 9 wherein said control systems module includes an electronic controller board, and wherein said electrical connecting means comprises a plurality of projecting pins electrically connected to said controller board and a plurality of mating jacks electrically connected to said transceiver board.

7. An improved radio comprising:

a control systems module;

a shielded RF module removably connected to said control systems module; and

split universal device contacts having a first part thereof associated with said control systems module and a second part thereof associated with said RF module,

said first and second parts being located physically proximate to each other on their respective modules such that a single multi-pronged plug can be electrically connected to both said first and second parts;

wherein said RF module comprises

a transceiver;

an antenna;
