Patent Images
1. A printed circuit board for a radio communication transceiver having electronic transmitter and receiver components secured to the board, the improvement comprising:
- a plurality of modules, wherein each said module is functionally unique and contains substantially all of the circuitry required to perform one of the major functions of the transmitter or receiver components, said modules including a voltage controlled oscillator module, a power amplifier module, a power control module and a phase-locked loop voltage regulator module,plural connecting elements for securing each of said modules to the circuit board, wherein the electrical and physical arrangement of said modules and connecting elements on said board are such that electrical testing of the unique function of each said module can be performed independently of the remaining said modules, andwherein said connecting elements extend through said board to form a plurality of test connections for connection to automatic test equipment for individually testing said major functions.
