1. A device comprising:
(a) a plurality of radio frequency (RF) switches, each of said RF switches operable with a plurality of frequency bands;
(b) at least one RF coupling device; and
(c) a processor programmed to selectively control operation of said plurality of RF switches based on an uplink signal from an electronic communication device electromagnetically coupled with said at least one RF coupling device,
wherein said plurality of radio frequency (RF) switches comprise:
(i) one or more low RF band (LRFB) switches operable in one or more low frequency bands under a particular frequency (F), and
(ii) one or more high RF band (HRFB) switches operable in one or more high frequency bands at or over said particular frequency (F), and
wherein said at least one RF coupling device comprises
(iii) at least one LRFB coupling device corresponding to said one or more low frequency bands under said particular frequency (F), and
(iv) at least one HRFB coupling device corresponding to said one or more high frequency bands at or over said particular frequency (F), and
wherein the one or more LRFB switches comprise a first LRFB switch and a second LRFB switch, and wherein the one or more HRFB switches comprise a first HRFB switch and a second HRFB switch, the device further comprising:
(a) a first low-noise amplifier (LNA) connected to said second LRFB switch, said first LNA for amplifying LRFB signals output by said second LRFB switch, and
(b) a second LNA connected to said second HRFB switch, said second LNA for amplifying HRFB signals output by said second HRFB switch.
