Abstract
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.
