MTK952 User Manual Dual Transmitter Mono - Stereo - Intercom Modulation SN: ________________ rev.06 (ref. FW 2.0) Date: 10 April 2015

MTK952 User Manual rev.06 1 BRIEF DESCRIPTION MTK952 is a versatile dual transmitter capable of working in a huge UHF bandwidth and of generating any kind of narrow-band modulations, with very high quality and low spurious emissions. Main features:  330 MHz Bandwidth (470 MHz – 800 MHz)  2400 user-defined frequencies (40 group by 60 freq.)  Stereo, mono, intercom audio modulation  Output power up to 2 Watt (/W option)  Analogue & digital input (AES3)  Redundant power supply 230/110 Vac & 12 VDC  DSP audio processing (40bit floating point / 2Gflops) with multi-companding  Direct Digital Synthesis (DDS) of signal for the highest flexibility and quality (> 70 dB stereo separation)s SWR (Stationary Wave Ratio) sensing on antenna outputs Above a schematic with the functional diagram of one transmitter of MTK952. MTK952 use extreme technologies like:  Direct Digital Synthesizer (DDS) DDS is a type of frequency synthesizer used for creating arbitrary waveforms from a single, fixed-frequency reference clock. A DDS has many advantages over its analog counterpart, the phase-locked loop (PLL), including much better frequency agility, improved phase noise, and precise control of the output phase across frequency switching transitions. The Direct Digital Synthesis (DDS) technology can generate virtually any kind of modulation while keeping an absolute phase accuracy.  Double conversion stage Using a double conversion and saw filter at IFs (intermediate frequencies) we can achieve a very low spurious emission and a great bandwidth agility (330 MHz).  Intermodulation cancelling power amplifiers PA module (power amplifiers) is designed with an exclusive circuitry that reduce the intermodulation generated by external carriers using a wideband phase cancelling design.  Digital audio with Shark™ DSP 40bit floating point & 2 Gflops power from Analog Device A very powerful Analog Design Shark DSP processor manages the audio with very low delay (< 1 ms) and emulates by software all companding and pre-emphasis effects.
