‘Monolithic Microwave Integrated Circuit’ (‘MMIC’) amplifiers that are any of the following: (a) Rated for operation at frequencies exceeding 2,7 GHz up to and including 6,8 GHz with a ‘fractional bandwidth’ of 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; (b) Rated for operation at frequencies exceeding 6,8 GHz up to and including 16 GHz with a ‘fractional bandwidth’ of greater than 10 %, and having any of the following: 1. A peak saturated power output greater than 10W (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 5W (37 dBm) at any frequency exceeding 8,5 GHz up to and including 16 GHz; (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 GHz up to and including 43,5 GHz, and with a ‘fractional bandwidth’ of greater than 10 %; (f) Rated for operation with a peak saturated power output greater than 31,62 mW (15 dBm) at any frequency exceeding 43,5 GHz up to and including 75 GHz, and with a ‘fractional bandwidth’ of greater than 10 %; (g) Rated for operation with a peak saturated power output greater than 10 mW (10 dBm) at any frequency exceeding 75 GHz up to and including 90 GHz, and with a ‘fractional bandwidth’ of greater than 5 %; or (h) Rated for operation with a peak saturated power output greater than 0,1 nW (– 70 dBm) at any frequency exceeding 90 GHz; Notes: 1. The status of the MMIC whose rated operating frequency includes frequencies listed in more than one frequency range is determined by the lowest peak saturated power output threshold. 2. This category does not apply to MMICs if they are specially designed for other applications, e.g., telecommunications, radar, automobiles.
