a. A band‑pass bandwidth of more than 0.5% of centre frequency; or
b. A band‑stop bandwidth of less than 0.5% of centre frequency;
3. A. 001. b. 6. Not used;
3. A. 001. b. 7. Converters and harmonic mixers, that are any of the following:
a. Designed to extend the frequency range of "signal analysers" beyond 90 GHz;
b. Designed to extend the operating range of signal generators as follows:
1. Beyond 90 GHz;
2. To an output power greater than 100 mW (20 dBm) anywhere within the frequency range exceeding 43.5 GHz but not exceeding 90 GHz;
3. A. 001. b. 7. c. Designed to extend the operating range of network analysers as follows:
1. Beyond 110 GHz;
2. To an output power greater than 31.62 mW (15 dBm) anywhere within the frequency range exceeding 43.5 GHz but not exceeding 90 GHz;
3. A. 001. b. 7. c. 3. To an output power greater than 1 mW (0 dBm) anywhere within the frequency range exceeding 90 GHz but not exceeding 110 GHz; or
d. Designed to extend the frequency range of microwave test receivers beyond 110 GHz.
3. A. 001. b. 8. Microwave power amplifiers containing "vacuum electronic devices" specified by 3A001.b.1. and having all of the following:
a. Operating frequencies above 3 GHz;
b. An average output power density to mass ratio exceeding 80 W/kg; and
c. A volume of less than 400 cm3;
Note: 3A001.b.8. does not apply to equipment designed or rated for operation in any frequency band which is "allocated by the ITU" for radio‑communications services, but not for radio‑determination.
3. A. 001. b. 9. Microwave Power Modules (MPMs) consisting of, at least, a travelling‑wave "vacuum electronic device", a "Monolithic Microwave Integrated Circuit" ("MMIC") and an integrated electronic power conditioner and having all of the following:
a. A 'turn‑on time' from off to fully operational in less than 10 seconds;
b. A volume less than the maximum rated power in Watts multiplied by 10 cm3/W; and
c. An "instantaneous bandwidth" greater than 1 octave (fmax. > 2fmin.) and having any of the following:
1. For frequencies equal to or less than 18 GHz, an RF output power greater than 100 W; or
2. A frequency greater than 18 GHz;
Technical Notes:
For the purposes of 3A001.b.9.:
                  1. To calculate the volume in 3A001.b.9.b., the following example is provided: for a maximum rated power of 20 W, the volume would be: 20 W x 10 cm3/W = 200 cm3.
