When designing a receiver or transmitter using discrete components

Achieving clean oscillations above about 300 MHz
(1 meter wavelength) from standard glass and metal vacuum tubes is difficult
due to interelectrode capacitances and self-inductance of internal wires and grid plates. Generating

of klystron, magnetron, and
ring oscillator tubes during World War II years. The UHF radio band spans from 300 MHz
to 3 GHz, and it is the upper end of the band where the wavelength is short enough
(3.93 inches | 10.0 cm for 3 GHz) to provide adequate spatial resolution

difficult and confusing for someone just being introduced to it. Combining specifications for gain,
power, and voltage (and current, but not so often) that mix dB, dBm, dBW,
