1 Introduction Due to its attractive features of low loss, low system cost, and compact size, RF co-design attempts to combine the capabilities of two microwave components into a single device. In order to decrease its loss and reduce its physical footprint has become more popular with the rapid advancement of modern wireless technologies [1, 2].

Abstract This work presents a compact electronically switchable filtering power divider (FPD) for Sub-6 GHz wireless front ends requiring adaptive and spectrum-flexible RF hardware. Conventional multi-band receivers rely on separate narrowband and wideband chains, resulting in increased loss, complexity, and circuit footprint.

1. Introduction Air pollution, a pervasive and escalating global challenge, poses severe threats to public health, particularly in densely populated urban areas. The intricate web of causative factors encompasses vehicular emissions, industrial activities, and the multifaceted consequences of climate change [1,2].
