1. A transmitter, comprising:
- a broadband up-converter configured to convert an input signal into a Radio Frequency (RF) signal having an output frequency, and to adjust the output frequency over a broadband frequency range containing multiple sub-bands;
a modular receptacle comprising an input interconnection adapter permanently coupled to the broadband up-converter and an output interconnection adapter coupled to an antenna, wherein the input interconnection adapter and the output interconnection adapter are each configured to removably receive a first power amplifier (PA), at a first instance, that covers a first sub-band in the broadband frequency range and to removably receive a second PA, at a second instance, in place of the first PA, that covers a second sub-band in the broadband frequency range; and
a diplexer configured to connect the antenna to the transmitter and to a receiver, wherein the diplexer is coupled to the output interconnection adapter.

Abstract
A transmitter includes an up-converter and a modular receptacle. The up-converter is coupled to convert an input signal into a Radio Frequency (RF) signal having an output frequency, and is configurable to adjust the output frequency over a frequency range containing multiple sub-bands. The modular receptacle includes a first interconnection adapter coupled to the up-converter and a second interconnection adapter for coupling to an antenna. The receptacle is configured to receive between the first and second interconnection adapters a Power Amplifier (PA), which is selected from a group of power amplifiers each covering a respective sub-band in the frequency range.

12. A method, comprising:
-
providing a pre-fabricated up-conversion assembly comprising a broadband up-converter configured to convert an input signal into a Radio Frequency (RF) signal having an output frequency and to adjust the output frequency over a broadband frequency range containing multiple sub-bands, and further comprising a modular Power Amplifier (PA) receptacle that includes an input interconnection adapter permanently coupled to the up-converter and an output interconnection adapter coupled to an antenna, wherein the input and output interconnection adapters are configured to removably receive a first PA, at a first instance, that covers a first sub-band in the broadband frequency range; affixing a diplexer to the output interconnection adapter, wherein the diplexer is configured to connect the antenna to a transmitter and to a receiver; coupling the first PA between the input and output interconnection adapters of the modular PA receptacle, so as to produce the transmitter covering the first sub-band; and removably receiving a second PA to replace the first PA, at a second instance, that covers a second sub-band in the broadband frequency range when a target value of the output frequency is outside of the first sub-band. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)
