Abstract

In this paper, a harmonic termination load network using a defected microstrip structure (DMS) for a high efficiency power amplifier is proposed and compared with a dumb-bell shaped defected ground structure (DGS) harmonic termination load network. The proposed structure is designed for a wideband code division multiple access (WCMDA) down-link applications operating at frequency of 2.11∼2.17 GHz. From the experiment, the attenuation of the DMS for the harmonic frequency (4.22∼6.51 GHz) is more than 27 dB. Comparing the defected area, the DMS occupies a quarter of the DGS defected area. The DMS has caused less electromagnetic interference (EMI) noise than the DGS due to no defected area in a ground plane. The ground problem of DGS can be overcome by using DMS.
