Abstract: A transceiver includes a transmit/receive terminal, a receiver input terminal, a plurality of impedance transformation networks coupled in series, a plurality of power amplifiers, and a controller. Each impedance transformation network has first and second ports. The impedance transformation networks include at least one selectable impedance transformation network having a resonant mode and a termination mode. The power amplifiers have outputs respectively coupled to the second ports of corresponding ones of the impedance transformation networks. In a receive mode, the controller selects the resonant mode for each selectable impedance transformation network and disables all power amplifiers. In a transmit mode, the controller enables a selected power amplifier and selects the resonant mode of any upstream selectable impedance transformation network, and selects the termination mode of a downstream selectable impedance transformation network.

Abstract: A transceiver comprises a transmit/receive terminal, a receiver input terminal, a scalable impedance network, a plurality of power amplifiers, and a receiver. The scalable impedance network is coupled between the transmit/receive terminal and the receiver input terminal and has a plurality of taps in an order between the transmit/receive terminal and the receiver input terminal, in which an impedance looking into any given tap toward the transmit/receive terminal is smaller than an impedance looking into a subsequent tap toward the transmit/receive terminal, if any, in the order. The plurality of power amplifiers are arranged in an order and have outputs respectively coupled to the plurality of taps of the scalable impedance network. A power of any given power amplifier is higher than a power of a subsequent power amplifier, if any, in the order. The receiver is coupled to the receiver input terminal.
