A radio frequency (RF) transceiver of the type having at least one radio frequency integrated chip (RFIC), a reference oscillator and a phase-locked oscillator, utilizes non-crystal resonator structures in place of crystal oscillators to produce the reference oscillator frequency functionality and the phase-locked oscillator frequency functionality. Film bulk acoustic resonator (FBAR) structures including bulk acoustic wave (BAW) resonators are monolithically integrated or flip chipped with the RFIC to reduce size, weight and cost of the transceiver. The RF transceiver may be a TDMA or CDMA transceiver.

Crystal-less oscillator transceiver

A function-oriented manufacturing approach in RF front-end architecture for use in a multi-band mobile phone. Electronic components in a front-end module, such as low-noise amplifiers that require the demanding silicon bipolar process, are fabricated separately from those components in an RF-ASIC that require the less demanding, yet more costly, Bi-CMOS process. When the transmission frequency band and the receiving band overlap, separate receiving antenna and transmitting antenna are used, instead of an antenna switch module with a duplexer, connected to separate bandpass filters for band selection. Differential Rx antennas are used so that the whole Rx-chain can be made differential. Furthermore, different impedances for Tx out and Rx in can be realized.

A method of fabricating a plurality of bulk acoustic wave (BAW) resonators on a single substrate, and the corresponding product, the BAW resonators having substantially different resonant frequencies, the method including the steps of: providing a substrate having an upper facing surface; depositing an isolation structure on the upper facing surface of the substrate; depositing a first metallic layer on the isolation structure, the first metallic layer serving as a bottom electrode; and depositing piezolayer material on the bottom electrode so as to have thicknesses corresponding to each of the different resonant frequencies, each different thickness located in a location where a resonator having a resonant frequency corresponding to the thickness is to be located. In one of several embodiments, the step of depositing piezolayer material on the bottom electrode itself includes the steps of: depositing piezolayer material to a thickness corresponding to the lowest frequency resonator; providing hard mask material over areas where the lowest frequency resonators are to be located; and removing the piezolayer material down to the thickness of the next higher frequency resonators. In some applications of the method, the isolation structure is an acoustic mirror, and the method further includes the step of providing the acoustic mirror, interposed between the substrate and the bottom electrode, according to a design that imparts to the acoustic mirror a desired reflection coefficient over a predetermined range of frequency including the substantially different resonant frequencies.

Stacked substrates using passive integration components formed in silicon or stainless steel substrates interconnect with active elements mounted on the surface of the substrate to form a miniaturized power amplification module. Metal filled vias pass through the layers and carry electrical signals to and from the active elements and passive components. The metal filled vias function as thermal transfer heat sinks to transfer heat away from the active elements and the module.

The invention relates to resonator structures of radio communication apparatus. According to the invention, at least one resonator structure and at least one switch structure are manufactured on the same substrate during the same process. This is especially advantageous when using bridge type BAW resonators and micromechanical switches, since the same process steps which are used for creating the bridge structures, can be used to create the micromechanical switch structure. Integration of switch structures and resonators on the same substrate allows the manufacture of very compact filter and resonator structures needed for multi-system mobile communication means. According to another aspect of the invention a special property of BAW resonators is utilized, namely that BAW resonators can be integrated on substrates which are commonly used for active circuitry, such as silicon (Si) and gallium arsenide (GaAs) surfaces. According to this aspect of the invention, the switches are realized with transistor structures using, for example, MESFET transistors.
