RF FRONT-END MODULE FOR PICOCELL AND MICROCELL BASE STATION TRANSCEIVERS

摘要

RF module 20 is configured for surface mounting directly to the front end of the picocells or microcells. Module including a plurality of electrical components and circuitry are mounted to define the transmit and receive sections of the individual RF signals board 22. Signal transmitting section is defined by at least a transmission band-pass filter 25, power amplifier 26, an isolator 28, a coupler 30, and the duplexer 34. Signal receiving section is defined by at least a duplexer 34, a reception low-pass filter 36, a low noise amplifier (39), and reception band-pass filter 40. Cover 45 is selected to cover the electrical components of the electrical components, except for at least the power amplifier. Power amplifier circuit board through the bottom-hole 136 allows the heat to be transmitted from the power amplifier. ; Picocells, micro-cells, the front end, directly surface mounted, RF module, a circuit board, the signal transmission section, the signal receiving section
