An annular electron beam;
                         b. A non‑axisymmetric electron beam; or
                         c. Multiple electron beams;
3. A. 001. b. 1. b. Crossed‑field amplifier "vacuum electronic devices" with a gain of more than 17 dB;
c. Thermionic cathodes designed for "vacuum electronic devices" producing an emission current density at rated operating conditions exceeding 5 A/cm² or a pulsed (non‑continuous) current density at rated operating conditions exceeding 10 A/cm²;
d. "Vacuum electronic devices" with the capability to operate in a 'dual mode'.

Technical Note:

For the purposes of 3A001.b.1.d., 'dual mode' means the "vacuum electronic device" beam current can be intentionally changed between continuous-wave and pulsed mode operation by use of a grid and produces a peak pulse output power greater than the continuous-wave output power.
3. A. 001. b. 2. "Monolithic Microwave Integrated Circuit" ("MMIC") amplifiers that are any of the following:

                   N.B.: For "MMIC" amplifiers that have an integrated phase shifter see 3A001.b.12.
a. Rated for operation at frequencies exceeding 2.7 GHz up to and including 6.8 GHz with a "fractional bandwidth" greater than 15%, and having any of the following:
1. A peak saturated power output greater than 75 W (48.75 dBm) at any frequency exceeding 2.7 GHz up to and including 2.9 GHz;
2. A peak saturated power output greater than 55 W (47.4 dBm) at any frequency exceeding 2.9 GHz up to and including 3.2 GHz;
3. A peak saturated power output greater than 40 W (46 dBm) at any frequency exceeding 3.2 GHz up to and including 3.7 GHz; or
4. A peak saturated power output greater than 20 W (43 dBm) at any frequency exceeding 3.7 GHz up to and including 6.8 GHz;
3. A. 001. b. 2. b. Rated for operation at frequencies exceeding 6.8 GHz up to and including 16 GHz with a "fractional bandwidth" greater than 10%, and having any of the following:
1. A peak saturated power output greater than 10 W (40 dBm) at any frequency exceeding 6.8 GHz up to and including 8.5 GHz; or
2. A peak saturated power output greater than 5 W (37 dBm) at any frequency exceeding 8.5 GHz up to and including 16 GHz;
3. A. 001. b. 2. c. Rated for operation with a peak saturated power output greater than 3 W (34.77 dBm) at any frequency exceeding 16 GHz up to and including 31.8 GHz, and with a "fractional bandwidth" of greater than 10%;
d. Rated for operation with a peak saturated power output greater than 0.1n W (‑70 dBm) at any frequency exceeding 31.8 GHz up to and including 37 GHz;
e. Rated for operation with a peak saturated power output greater than 1 W (30 dBm) at any frequency exceeding 37
