Abstract
A front end module for use in a wireless base station such as a picocell includes a housing defining a cavity for a substrate. A first section on the substrate defines a signal transmit path and includes at least the following discrete electronic components: a bandpass filter, a power amplifier, and a coupler. A second section on the substrate defines a signal receive path and includes at least the following discrete electronic components: a bandpass filter and a low-noise amplifier. A switch on the substrate interconnects the first and second sections to an antenna terminal and a wall in the housing extends through a slot in the substrate to isolate the components in the first and second sections. Terminals extend through an exterior wall of the housing and into contact with the substrate.
