MIL-STD-188-164 Interoperability Of Shf Satellite Communications TerminalsThis standard establishes mandatory Radio Frequency/Intermediate Frequency RF/IF and associated interface requirements applicable to Satellite Communications SATCOM Earth Terminals ET operating over military X-band and Ka-band Super High Frequency SHF channels. Military unique requirements for ET that may operate over commercial C-band, Ku-band, and Ka-band are included. Equipment developers may exceed the requirements herein to satisfy specific program requirements, provided that interoperability is maintained. Thus, incorporating additional standard and nonstandard capabilities and interfaces is not precluded. Existing SHF SATCOM terminals need not conform to this MIL-STD unless they undergo a modernization program.

±  1.5 dB over any 120 MHz or smaller instantaneous bandwidth (10 MHz < instantaneous bandwidth < 120 MHz)

±  2.0 dB for each output frequency band listed in table I (NOTE: This may be exceeded if the terminal meets all

implementation loss requirements mandated by the appropriate

satellite communications systems expert (SSE).

4.2.9 AC power line.    The sum of the fundamental and all harmonic components of the alternating current (AC) line frequency shall not exceed -30 dBc.

4.2.10 Single sideband.  The single sideband sum (added on

a power basis) of all other individual spurious components shall not exceed -36 dBc.

4.2.11 Phase noise.  The single sideband power spectral density of the continuous phase noise component shall comply with the envelope defined on figure 1.  If specific points associated with the measured phase noise plot exceed the figure

1 envelope, then the following two conditions shall be met:

d. The single sideband phase noise due to the continuous component, when integrated over the bandwidth from 10-Hz to

16-kHz relative to carrier center frequency, shall be less than 3.4 degrees-RMS (two-sided value of 4.8 degrees-RMS).
