Abstract

This research outlines the conception and analysis of two Filtering Power Divider (FPD) models, essential in efficacious RF/microwave applications [1]. The innovative approach amalgamates filtering components to concurrently achieve power division and signal filtration, thereby offering a versatile solution for wireless and satellite communication systems [2]. Design 1, a three-port configuration, exhibited commendable input matching (S 11 of −22dB) at 2.4GHz, along with satisfactory port isolation (S 21 and S 31 at −3.1dB) [3]. Design 2, a five-port, ring-shaped layout, manifested superior performance with improved input matching (S 11 of −27dB) and greater isolation (S 21 , S 31 at −3.15dB, S 32 at −30dB). Both models displayed solutions to Out of Band Reflection (OBR) [4], with Design 2 featuring an Absorptive filter to curtail stray signals, underscoring its adaptability and potential for enhanced isolation. The choice between the designs should consider application-specific requisites and balance trade-offs between complexity, cost, and performance. The completed FPD project offers an agile, compact solution apt for a gamut of RF/microwave applications, especially for wireless devices operating at 2.5GHz [5].
