a second band switching network comprising a second plurality of RF switches (426a-426b), each RF switch of the second plurality of RF switches being connected to the second port (427a 2 -427f 2) of a respective one of the plurality of RF filters (424a-424f) and coupled to a common antenna port at which RF energy is communicated to or from an antenna, the second band switching network being responsive to at least a second control signal which selectively controls which of the plurality of RF filters (424a-424f) is connected to the common antenna port; a transmit/receive, hereinafter T/R, switching network comprising at least one receiver RF switch (420a, 420b) that is provided in addition to the first and second plurality of RF switches, the at least one receiver RF switch (420a, 420b) being connected directly to at least one of the first ports (427a 1 -427f 1), among the ports at which the first plurality of RF switches is connected and which is also a T/R port, and coupled to a receiver port at which received RF energy is communicated to a receiver, the at least one receiver RF switch (420a, 420b) being responsive to at least a third control signal to selectively permit the received RF energy arriving at the at least one first port (427a 1 -427f 1) to be communicated to the receiver; and a switch control system which controls the second band-switching network to selectively communicate received RF energy from the common antenna port to the T/R port which is connected to the receiver port; wherein each of said first and second plurality of RF switches (422a-422f, 426a-426b) and the at least one receiver RF switch (420a, 420b) are PIN diodes switches having a PIN diode in series with a signal path, whereby no more than two PIN diodes are present in the signal path between the common transmitter port and the common antenna port when any of the RF filters (424a-424f) is in use. a plurality of RF filters (424a-424f), each having a first and second port (427a 1 -427f 1, 427a 2 -427f 2); a first band switching network comprising a first plurality of RF switches (422a-422f), each RF switch of the first plurality of RF switches being connected to the first port (427a 1 -427f 1) of a respective one of the plurality of RF filters (424a-424f) and coupled to a common transmitter port at which transmitter RF energy is received from a transmitter, the first plurality of RF switches (422a-422f) being responsive to at least a first control signal to selectively direct said transmitter RF energy to a selected one of the plurality of RF filters (424a-424f); a second band switching network comprising a second plurality of RF switches (426a-426b), each RF switch of the second plurality of RF switches being connected to the second port (427a 2 -427f 2) of a respective one of the plurality of RF filters (424a-424f) and coupled to a common antenna port at which RF energy is communicated to or from an antenna, the second band switching network being responsive to at least a second control signal which selectively controls which of the plurality of RF filters (424a-424f) is connected to the common antenna port; a transmit/receive, hereinafter T/R, switching network comprising at least one receiver RF switch (420a, 420b) that is provided in addition to the first and second plurality of RF switches, the at least one receiver RF switch (420a, 420b) being connected directly to at least one of the first ports (427a 1 -427f 1), among the ports at which the first plurality of RF switches is connected and which is also a T/R port, and coupled to a receiver port at which received RF energy is communicated to a receiver, the at least one receiver RF switch (420a, 420b) being responsive to at least a third control signal to selectively permit the received RF energy arriving at the at least one first port (427a 1 -427f 1) to be communicated to the receiver; and a switch control system which controls the second band-switching network to selectively communicate received RF energy from the common antenna port to the T/R port which is connected to the receiver port;
