abstract

  • In this paper, we design and analyze the receiver channel of a glass interposer for a dual band Wi-Fi front end module (FEM). In RF systems, a RF sensitivity is the most important specification for a system performance and reliability. To guarantee a target RF sensitivity of the RF system, it is important to maintain a 50 Ohm impedance matching for RF channels. The 50 Ohm impedance matching of various transmission line structures is completely conducted for each layer of the glass interposer in a low band (2.4GHz - 2.5GHz) and high band (4.9GHz - 5.85GHz) respectively. Channel types for each layer are determined considering design rules and constraints. Moreover, we locate ground TGVs near signal TGVs as close as possible to suppress a ground-ground cavity resonance effect in the low band and high band. In order to test a suppression of the ground-ground cavity resonance, simulations that compare pitches between a ground TGV and signal TGV are conducted. Design considerations of receiver channels were analyzed and characterized by simulation results of channel insertion losses.
