§ 15.204 External radio frequency power amplifiers and antenna
(a) Except as otherwise described in paragraphs (b) and (d) of this
section, no person shall use, manufacture, sell or lease, offer for
sale or lease (including advertising for sale or lease), or import,
ship, or distribute for the purpose of selling or leasing, any external
radio frequency power amplifier or amplifier kit intended for use with
a part 15 intentional radiator.
(b) A transmission system consisting of an intentional radiator, an
external radio frequency power amplifier, and an antenna, may be
authorized, marketed and used under this part. Except as described
otherwise in this section, when a transmission system is authorized as
a system, it must always be marketed as a complete system and must
always be used in the configuration in which it was authorized.
(c) An intentional radiator may be operated only with the antenna with
which it is authorized. If an antenna is marketed with the intentional
radiator, it shall be of a type which is authorized with the
intentional radiator. An intentional radiator may be authorized with
multiple antenna types. Exceptions to the following provisions, if any,
are noted in the rule section under which the transmitter operates,
e.g., § 15.255(b)(1)(ii) of this part.
(1) The antenna type, as used in this paragraph, refers to antennas
that have similar in-band and out-of-band radiation patterns.
(2) Compliance testing shall be performed using the highest gain
antenna for each type of antenna to be certified with the intentional
radiator. During this testing, the intentional radiator shall be
operated at its maximum available output power level.
(3) Manufacturers shall supply a list of acceptable antenna types with
the application for equipment authorization of the intentional
(4) Any antenna that is of the same type and of equal or less
directional gain as an antenna that is authorized with the intentional
radiator may be marketed with, and used with, that intentional
radiator. No retesting of this system configuration is required. The
marketing or use of a system configuration that employs an antenna of a
different type, or that operates at a higher gain, than the antenna
authorized with the intentional radiator is not permitted unless the
procedures specified in § 2.1043 of this chapter are followed.
(d) Except as described in this paragraph, an external radio frequency
power amplifier or amplifier kit shall be marketed only with the system
configuration with which it was approved and not as a separate product.
(1) An external radio frequency power amplifier may be marketed for
individual sale provided it is intended for use in conjunction with a
transmitter that operates in the 902-928 MHz, 2400-2483.5 MHz, and
5725-5850 MHz bands pursuant to § 15.247 of this part or a transmitter
that operates in the 5.725-5.825 GHz band pursuant to § 15.407 of this
part. The amplifier must be of a design such that it can only be
connected as part of a system in which it has been previously
authorized. (The use of a non-standard connector or a form of
electronic system identification is acceptable.) The output power of
such an amplifier must not exceed the maximum permitted output power of
its associated transmitter.
(2) The outside packaging and user manual for external radio frequency
power amplifiers sold in accordance with paragraph (d)(1) of this
section must include notification that the amplifier can be used only
in a system which it has obtained authorization. Such a notice must
identify the authorized system by FCC Identifier.
