Eimac 2-01C UHF diode
The Eimac 2-01C is a small, closely-spaced, low-capacitance, high-vacuum diode designed for use through the ultra-high frequencies. In measurement work, it is well suited to mounting in a probe and will maintain accuracy in the order of ±1db up to 700MHz. It is useful as an indicator at frequencies as high as 3GHz. It is used as the detector diode in an HP 410B VTVM.
