The requirements of two‐way radio applications in the wideband operating frequency are stringent, particularly for the power amplifier (PA) design. A novel design method for a wideband PA matching network for two‐way radio applications is proposed. The design method begins with identifying an initial guess of the matching network from the theoretical analysis, followed by a practical design methodology to realise the design in the compact form factor and low cost implementation. Experimental results demonstrated an output power of ∼7 W and an efficiency of about 65%, demonstrated high power performance (including stable operation and ruggedness) from 270 to 560 MHz running at a low DC supply of 7.2 V (with LDMOS device technology).
