A multiple frequency signal generator for 802.11a/b/g VoWLAN type applications using organic packaging technology

This paper proposes a signal generator that simultaneously generates multiple frequencies while using the same set of passive components. The first example demonstrates the capability of simultaneously generating 2.45GHz and 5.2 GHz (WLAN a/b/g). Additionally, an oscillator capable of concurrently generating 900 MHz and 1.9 GHz (GSM and DCS-1800 band) is also presented. This paper uses the theory of multi-resonant passives and shows their immediate effects on different topologies of signal generators that generate signals for two or more frequency bands. In addition, measured and simulated results of individual blocks of such a simultaneous signal generator, such as, filters, individual oscillators, and feedback networks, are demonstrated.
