    • A dual-range crystal oscillator module comprises lower and upper wiring board panels each having a component side, a surface mount side, a central portion and an outer edge portion including a plurality of input-output contacts. A lower set of crystal oscillator components is mounted to the lower wiring board panel such that the lower set and the lower wiring board panel define a first crystal oscillator circuit. An upper set of crystal oscillator components is mounted to upper wiring board panel such that the upper set of crystal oscillator components and the upper wiring board panel together define a second crystal oscillator circuit. A side-wall frame is attached between the upper and the lower wiring boards providing connections between the input-output contacts of the upper wiring board panel and the input-output contacts of the lower wiring panel.

    • An RF module adapted for direct surface mounting to the top surface of the front end of the motherboard of a picocell. The module comprises a printed circuit board having a plurality of direct surface mounted electrical components defining respective signal transmit and receive sections for RF signals. The signal transmit section is defined by at least a transmit bandpass filter, a power amplifier, an isolator, a coupler, and a duplexer. The signal receive section is defined by at least the duplexer, a receive low pass filter, a low-noise amplifier, and a receive bandpass filter. A lid covers selected ones of the electrical components except for at least the power amplifier. A plurality of through-holes defined in the printed circuit board below the amplifier allow for the dissipation of heat created by the amplifier. At least one aperture in the board is adapted to accept a screw or the like for securing the module to the motherboard of the picocell.

    • An RF module for use in an RF signal transceiver system. In one embodiment, the RF module comprises a substrate having at least a duplexer filter, first and second bandpass filters and first and second low noise amplifiers mounted thereon. The substrate includes respective edges having respective RF signal input/output and supply voltage terminals defined therein. The overall dimensions of the substrate and/or the location of the respective terminals have been predetermined in a manner which allows the same size substrate with the same terminal locations to be used for several different air interfaces such as, for example, EGSM, GSM 850, DCS, and PCS applications, irrespective of a specific air interface need for differently sized and/or additional filters.
