The wide bandwidth transceiver includes a receiver section, a transmitter section, and a local oscillation module. The receiver section includes a 1<st >receiver intermediate frequency (IF) stage, a receiver switch module, and a 2<nd >receiver IF stage. The 1<st >receiver IF stage is operably coupled to convert a 1<st >inbound radio frequency (RF) signal into a 1<st >inbound IF signal based on a 1<st >local oscillation of the local oscillation module. The receiver switch module passes either the 1<st >inbound IF signal or a 2<nd >inbound RF signal, which have similar carrier frequencies, to the 2<nd >receiver IF stage. The 2<nd >receiver IF stage receives the selected signal from the receiver switch module and based on a 2<nd >local oscillation converts the selected signal into a low intermediate frequency signal. The transmitter section includes a 1<st >transmitter intermediate frequency (IF) stage, a 2<nd >transmitter IF stage, a power amplifier and a transmitter switch module. The 1<st >transmitter IF stage is operably coupled to convert an outbound low IF signal into a 1<st >outbound radio frequency (RF) signal based on the 2<nd >oscillation. The 2<nd >transmitter IF stage, when operably coupled, converts the 1<st >outbound RF signal into a 2<nd >outbound RF signal based on the 1<st >local oscillation. The transmitter switching module couples either the 1<st >outbound RF signal or the 2<nd >outbound RF signal to the power amplifier.
