Abstract
An RF Rx 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 discrete electrical components defining a receive (Rx) section and path for RF signals. The signal receive section is defined by at least the following elements located under a lid which is attached to the surface of the board: a duplexer, a receive low pass filter, a low-noise amplifier, and a receive bandpass filter. 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.
