§ 95.987 CBRS additional requirements.
Each CBRS transmitter type must be designed to satisfy all of the
additional requirements in this section.
(a) Transmit frequency capability. Each CBRS transmitter type must be
designed to transmit only on one or more of the channels listed in
§ 95.963. No CBRS transmitter type will be certified for use in the CBRS
service if it is capable of transmitting on any frequency or channel
other than those listed in § 95.963, unless such transmitter type is
also certified for use in another radio service for which the frequency
capability is authorized and for which FCC certification is also
required.
(b) Frequency determining circuitry. All frequency determining
circuitry (including crystals) and programming controls in each CBRS
transmitter type must be internal to the transmitter and must not be
accessible from the operating panel or from the exterior of the
transmitter enclosure.
(c) Final amplifier component ratings. The dissipation rating of all
the semiconductors or electron tubes which supply RF power to the
antenna terminals of each CB transmitter must not exceed 10 Watts. For
semiconductors, the dissipation rating is the greater of the collector
or device dissipation value established by the manufacturer of the
semiconductor. These values may be temperature de-rated by no more than
50 °C. For an electron tube, the dissipation rating is the Intermittent
Commercial and Amateur Service plate dissipation value established by
the manufacturer of the electron tube.
(d) External controls. Only the external transmitter controls,
connections or devices listed in this paragraph are allowed to be
incorporated in a CBRS transmitter type. The FCC, however, may
authorize additional controls, connections or devices after considering
the functions to be performed by such additions.
(1) Primary power connection. External power supplies may be used.
(2) Microphone connection.
(3) Antenna connection.
(4) Headphone and speaker output connections and related selector
switch.
(5) On-off switch for primary power to the transmitter. This switch may
be combined with receiver controls such as the receiver on-off switch
and volume control.
(6) Upper/lower sideband selector switch (for a transmitter that is
capable of transmitting SSB emissions).
(7) Carrier level selector control (for a transmitter that is capable
of transmitting SSB emissions). This control may be combined with the
sideband selector switch.
(8) Channel selector switch.
(9) Transmit/receive selector switch.
(10) Meter(s) and selector switch(es) for monitoring transmitter
performance.
(11) Pilot lamp(s), meter(s), light emitting diodes, liquid crystal
devices or other types of visual display devices to indicate the
presence of RF output power or that the transmitter control circuits
are activated to transmit.
