7/10/02Revision 1.1 201545 Truckee 2.4GHz FM TV Transmitter RF Module operational Description and Specification V ALON T ECHNOLOGY , LLC1of 47/10/02 sdr 1.0 General Description: The Truckee 2.4GHz FM Transmitter is an RF module that is capable transmitting video and audio NTSC or PAL television signals in the 2400-2485MHz ISM frequency band. The transmitter accepts a composite video signal from any video source. The transmitter also accepts audio from any high level source. The transmit RF output frequency and audio sub-carrier frequency are set by the 3-wire, serial interface. Output power this transmitter is approximately 1mW. 2.0 Transmitter Topology Figure 1 above; shows the block of the FM transmitter topology. The transmitter is essentially PLL stabilized VCO, operating at the output frequency, that is a directly modulated by the video signal. The VCO is controlled by a PLL and tuneable over the 2400- 2485MHz ISM band. The input composite video signal is filtered by a video pre-emphasis network and applied to tuning port of the RF VCO to provide wideband FM modulation. The video deviation is not adjustable and is set by design. The RF VCO is controlled by the RF section of the dual synthesizer/PLL integrated circuit. This is a integer-N PLL with very low loop bandwidth. The audio signal is filtered by an audio pre-emphasis network and applied directly to the one of the two tuning ports of the 6.0MHz sub-carrier VCO to provide an FM modulated audio sub-carrier. The audio deviation is set by design. The frequency of the sub- carrier VCO is tuned and stabilized by the digital synthesizer/PLL through the other VCO tuning port. The 6 MHz audio sub-carrier is then amplitude limited by the diode limiter circuit in order to maintain a constant sub-carrier level. The limited sub-carrier signal is then amplified and buffered by the sub-carrier buffer amplifier in order to increase the signal level and isolate the VCO. The buffered sub-carrier is then filtered to remove harmonics by a narrow band bandpass filter. A secondary output from the buffer amplifier is further amplified and amplitude limited by the PLL Amp. The PLL Amp squares and limits the amplitude of the 6.0MHz sub-carrier signal in order to ensure positive clocking of the Synthesizer/PLL. The filtered sub-carrier output from the bandpass filter is combined with the pre-emphasised video signal, and the buffered RF loop filter signal at the summing node at the VCO tuning port. The summing node is simply a resistive adder circuit that combines the tuning signal with the video and audio sub-carrier modulation in the correct proportion for proper deviation and frequency control of the VCO. The RF VCO output at 2.4GHz is further amplified to provide an output level of approximately -0dBm to the antenna. The output lowpass filter removes the harmonics created by the VCO and amplifiers. The antenna is a dipole antenna realised on a FR4 PCB with about 1dBi gain.
