Working Principle
The TRF37B75EVM is based on the \'wideband\' transmitter format from TI which works through the 16 MHz bandwidth. The board-level evaluation platform makes use of four key components. The first component is the Voltage controlled oscillator (VCO). It produces a signal at the specified frequency which is then mixed with a signal from the direct synthetic modulated local oscillator (DSMLO) to form the carrier. The second component is the direct analog modulation path, which uses a process to control the amplitude, frequency, and phase shift of the signal in order to modulate it. The third component is the gain and loss adjustment circuitry used to obtain an optimal signal level for accurate data transfer. The fourth component is the temperature controlled voltage controlled oscillator (TCVCXO) which allows for the adjustment of the oscillator\'s frequency in order to keep it stable over a range of temperatures.
The TRF37B75EVM has a number of features that enable it to fulfill its purpose as an evaluation platform, including the ability to support a wide range of modulation schemes and bandwidths, direct synthetic modulated local oscillator inputs, compatible with single ended and differential inputs, and gain and loss adjustment for optimal design. The platform also provides a procedure to select the optimal supply voltage, which is necessary for accurate data transfer. This feature means that the user can easily optimize the path of their signal as required for their application.
