b. A "fractional bandwidth" of 5% or greater for any channel;
3. A. 001. b. 12. c. Any planar side with length d (in cm) equal to or less than 15 divided by the lowest operating frequency in GHz [d ≤ 15cm*GHz*N/fGHz] where N is the number of transmit or transmit/receive channels; and
3. A. 001. b. 12. d. An electronically variable phase shifter per channel.

              Technical Notes:

              For the purposes of 3A001.b.12.:
                  1. A 'transmit/receive module' is a multifunction "electronic assembly" that provides bi-directional amplitude and phase control for transmission and reception of signals.
                  2. A 'transmit module' is an "electronic assembly" that provides amplitude and phase control for transmission of signals.
                  3. A 'transmit/receive MMIC' is a multifunction "MMIC" that provides bi-directional amplitude and phase control for transmission and reception of signals.
                  4. A 'transmit MMIC' is a "MMIC" that provides amplitude and phase control for transmission of signals.
                  5. 2.7 GHz should be used as the lowest operating frequency (fGHz) in the formula in 3A001.b.12.c. for transmit/receive or transmit modules that have a rated operation range extending downward to 2.7 GHz and below [d≤15cm*GHz*N/2.7 GHz].

                  6. 3A001.b.12. applies to 'transmit/receive modules' or 'transmit modules' with or without a heat sink. The value of d in 3A001.b.12.c. does not include any portion of the 'transmit/receive module' or 'transmit module' that functions as a heat sink.
                  7. 'Transmit/receive modules', or 'transmit modules', or 'transmit/receive MMICs' or 'transmit MMICs' may or may not have N integrated radiating antenna elements where N is the number of transmit or transmit/receive channels.
3. A. 001. c. Acoustic wave devices as follows and specially designed components therefor:
1. Surface acoustic wave and surface skimming (shallow bulk) acoustic wave devices, having any of the following:
a. A carrier frequency exceeding 6 GHz;
b. A carrier frequency exceeding 1 GHz, but not exceeding 6 GHz and having any of the following:
1. A 'frequency side‑lobe rejection' exceeding 65 dB;
2. A product of the maximum delay time and the bandwidth (time in µs and bandwidth in MHz) of more than 100;
3. A bandwidth greater than 250 MHz; or
4. A dispersive delay of more than 10 µs; or
3. A. 001. c. 1. c. A carrier frequency of 1 GHz or less and having any of the following:
3. A. 001. c. 1. c. 1. A product of the maximum delay time and the bandwidth (time in µs and bandwidth in MHz) of more than 100;
2. A dispersive delay of more than 10 µs; or
3. A 'frequency side‑lobe rejection' exceeding 65 dB and a bandwidth greater than 100 MHz;
Technical Note:
For the purposes of 3A001.c.1., 'frequency side-lobe rejection' is the maximum rejection
