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.
2. The 'turn-on time' in 3A001.b.9.a. refers to the time from fully-off to fully operational, i.e., it includes the warm-up time of the MPM.
3. A. 001. b. 10. Oscillators or oscillator assemblies, specified to operate with a single sideband (SSB) phase noise, in dBc/Hz, less (better) than ­(126 + 20log10F ‑ 20log10f) anywhere within the range of 10 Hz ≤ F ≤ 10 kHz;
Technical Note:
For the purposes of 3A001.b.10., F is the offset from the operating frequency in Hz and f is the operating frequency in MHz.
3. A. 001. b. 11. 'Frequency synthesiser' "electronic assemblies" having a "frequency switching time" as specified by any of the following:
a. Less than 143 ps;
b. Less than 100 µs for any frequency change exceeding 2.2 GHz within the synthesised frequency range exceeding 4.8 GHz but not exceeding 31.8 GHz
c. Not used;
d. Less than 500 µs for any frequency change exceeding 550 MHz within the synthesised frequency range exceeding 31.8 GHz but not exceeding 37 GHz;
e. Less than 100 µs for any frequency change exceeding 2.2 GHz within the synthesised frequency range exceeding 37 GHz but not exceeding 75 GHz; or
f. Less than 100 μs for any frequency change exceeding 5.0 GHz within the synthesised frequency range exceeding 75 GHz but not exceeding 90 GHz; or
g. Less than 1 ms within the synthesised frequency range exceeding 90 GHz;
Technical Note:
For the purposes of 3A001.b.11., a 'frequency synthesiser' is any kind of frequency source, regardless of the actual technique used, providing a multiplicity of simultaneous or alternative output frequencies, from one or more outputs, controlled by, derived from or disciplined by a lesser number of standard (or master) frequencies.
                   N.B.: For general purpose "signal analysers", signal generators, network analysers and microwave test receivers, see 3A002.c., 3A002.d., 3A002.e. and 3A002.f., respectively.
3. A. 001. b. 12. 'Transmit/receive modules', 'transmit/receive MMICs', 'transmit modules', and 'transmit MMICs', rated for operation at frequencies above 2.7 GHz and having all of the following:
3. A. 001. b. 12. a. A peak saturated power output (in watts), Psat, greater than 505.62 divided by the maximum operating frequency (in GHz) squared [Psat>505.62 W*GHz2/fGHz2] for any channel;
3. A. 001. b. 12. 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
