MHz300

MHz300 is a fictional or illustrative designation used in electronics education and documentation to refer to devices, modules, or experiments that operate near 300 megahertz. It is not a specific standard or widely marketed product; rather, instructors and textbooks use MHz300 as a convenient shorthand to discuss concepts in radio frequency design at the lower end of the ultra high frequency (UHF) band.

In typical MHz300 reference designs, the core may include a frequency source such as a voltage-controlled oscillator (VCO) or a phase-locked loop (PLL) synthesizer, an RF signal path, and an output buffer with an impedance-matching network tuned to 50 ohms. Designers emphasize filtering and spurious suppression, gain staging, and proper shielding to achieve a clean spectrum. Power supply decoupling, thermal management, and mechanical enclosure considerations are also important for reliable operation at these frequencies.

Applications of the MHz300 concept are mainly educational and prototyping oriented. It serves as a target for labs on modulation, spectrum analysis, and link budgeting, as well as a practical reference for building small wireless transceivers or test signal generators in a classroom or hobbyist setting. Users should be aware that transmitting in the 300 MHz region is subject to regulatory rules that vary by country and may require licenses or permissions.

Notes: MHz300 is not tied to a single product line and does not represent a real-market device. It is primarily an instructional placeholder to discuss RF design at approximately 300 MHz.
