## Product Categories

### Magnetrons
Magnetrons are vacuum tubes that generate microwave energy through the interaction of electron streams with a magnetic field. PartnerTubes supplies CW (continuous wave) and pulse magnetrons for industrial heating, medical linear accelerators, radar, and scientific applications.

Key products: YJ1600 (CW S-band magnetron, 1.5 kW), M1568BS (pulse magnetron for radar).

### RF Power Grid Tubes
RF power grid tubes (triodes, tetrodes, pentodes) are used in high-power RF amplifiers for FM/TV broadcast transmitters, industrial RF heating, scientific accelerators, and defense systems. PartnerTubes stocks and supplies grid tubes including the RS2048CJC tetrode.
