An integrated differential high power amplifier-radiator array that overcomes the prior art impedance match issues is described. An impedance matching balun is used to feed a high output impedance, differential HPA, which in turn drives a wide band radiator or array of radiators having a matching input impedance to provide a highly efficient, compact transmit system. In one exemplary embodiment, the HPA may be a high impedance Class-B HPA configured as a push-pull cascode amplifier. A high impedance isolator or circulator may be used between the HPA and the radiator. One of ordinary skill in the art will readily appreciate that a receive implementation, using a properly matched low noise amplifier in place of the HPA, is also possible. Similarly, with the addition of a slotline circulator, transceiver operation is also attainable with the addition of an impedance matched receive chain.
