Output interface: SMA female connector for reliable RF connections and broad compatibility with standard test gear. Output frequency: 12.5 kHz to 200 MHz. F1 and F2 share a phase-locked loop, with a configurable division ratio for flexible frequency synthesis. Supply voltage: 5 V for easy integration with common 5 V systems and microcontroller projects. Why this matters: provides a versatile RF source for bench testing, calibration, and development. The shared PLL and configurable division ratio let you reach precise frequencies without juggling multiple oscillators. Performance and compatibility: wide frequency range with a standard SMA interface supports common RF workflows. The PLL-based design offers stable output suitable for measurement and experimentation, while the simple 5 V supply reduces wiring and power considerations. Use scenarios: - RF test bench: generate reference signals for receivers, filters, and RF front-end evaluation. - Wireless module development: validate transmit chains and calibrate up/down converters in a controlled signal path. - PLL-based prototyping: explore division ratio effects and frequency synthesis in lab experiments and educational projects.
