Abstract
The invention allows for a common integrated circuit PHY of a wireless modem to be used with different RF sections for making different modems by providing different RF adjustment interfaces. The RF adjustment interfaces can be provided by programmable hardware, and in some cases the same programmable hardware that is used for at least some of the MAC section of the modem.
Claims10
A wireless modem comprising:
- (a) an RF section adapted to be connected to an antenna and having a set of controllable components affecting wireless signal reception and/or transmission, an intermediate frequency (IF) input and an intermediate frequency (IF) output;
- (b) a physical layer (PHY) module receiving said IF output and generating said IF input, said PHY module comprising a predetermined set of RF adjustment signals, said PHY module being provided on an integrated circuit separately from said RF section;
- and
- (c) an RF adjustment control interface module receiving said predetermined set of RF adjustment signals and providing control signals to said set of controllable components affecting wireless signal reception and/or transmission of 'said RF section, said RF adjustment control interface module being a separate device from said PHY module and said RF section.

A method of manufacturing wireless modems comprising:
- (a) providing a common physical layer (PHY) module receiving said IF output and generating said IF input, said PHY module comprising a predetermined set of RF adjustment signals;
- (b) providing a first RF section adapted to be connected to an antenna and having a first set of controllable components affecting wireless signal reception and/or transmission, an intermediate frequency (IF) input and an intermediate frequency (IF) output;
- (c) providing a second RF section adapted to be connected to an antenna and having a second set of controllable components affecting wireless signal reception and/or transmission, an intermediate frequency (IF) input and an intermediate frequency (IF) output;
- (d) providing a first RF adjustment control interface module receiving said predetermined set of RF adjustment signals and able to providing control signals to said first set of controllable components affecting wireless signal reception and/or transmission of said RF section;
- (e) providing a second RF adjustment control interface module receiving said predetermined set of RF adjustment signals and able to providing control signals to said second set of controllable components affecting wireless signal reception and/or transmission of said RF section;
- (f) combining said first RF section with said common PHY module and said first interface module to manufacture first modems;
- and
- (g) combining said second RF section with said common PHY module and said second interface module to manufacture second modems.
