Output And External Clock Interface: SMA-(Internal Screw Hole)On-Board High Precision 25MHz 0.5 Opm Tcxo (Can Also Be Replaced By Yourself Or External Crystal)Output Frequency Range: Internal Vco Frequency Of 3-6GHz, 3ghz Or Less For The Frequency Divider. Full Touch Screen Frequency InputOutput Amplitude: -4 To 5dBm, 4-Speed Touch Screen Control.Output Frequency Mode: Point Frequency, Sweep Frequency Optional Touch Screen Controlwith an external reference clock oscillator and which way filter MAX2870 can constitute a high-performance frequency synthesizer to generate 23.5MHz to 6000MHz frequency range clock, well can maintain excellent phase noise and spurious indicators. Internal multiplexed integrated covering the 3000MHx to 6000MHz range and 1-128 output dividers are used to realize ultra-wide frequency range clock outputs. Compatible with 1.8V control logic 1. MAX2870 for ultra-wideband phase-locked loop (PLL), integrated voltage-controlled oscillator (VCO), to work in integer and fractional N frequency division modes.2. RF signal source module is characterized by the on-board high-precision 25MHz 0.5 ppm TCXO, the internal VCo base frequency output frequency range of 3-6GHz, 3GHz the base frequency crossover.3. The RF signal source module for the full touch screen frequency queuing, the output frequency mode for the point frequency, sweep frequency selectable4. RF signal source using lead-free, RoHS-compliant 5mmx5mm, 32TQFN package, the operating temperature range extends to 40 to 85C.5.
