Summary:
This paper presents a new design of a push-pull power amplifier (PA) structure integrated in a Vivaldi antenna. This structure responds to the demand of power and linearity required by modern wireless communication systems. The new approach presented here is based on a microstrip to slotline transition aiming to divide and combine the transmitted signal. This concept is applied here for the design of a compact push-pull PA in the 5GHz Wireless-LAN (IEEE 802.11a) frequency band. The design based on the low-cost FR4 substrate has been electromagnetically fully simulated using a commercial software.
