The Read diode is a member of a larger class of oscillators, referred to as avalanche diodes, ATT (avalanche transit time) diodes, or IMPATT diodes which were introduced in 1965.
Millimeter-wave IMPATT diodes which, under controlled conditions, have emitted a continuous wave at 150 GHz became the power source for waveguide transmission, emitting frequencies as high as 110 GHz with 100 milliwatts of power.
