RF6559

4.0V TO 4.5V, 915MHZ ISM BAND

TRANSMIT/RECEIVE MODULE

The RF6559 front end module is intended for use in 915MHz AMR solutions. The

RF6559 addresses the need for aggressive size reduction for a typical 915MHz

AMR front end design and greatly reduces the number of components outside the

RF6559 thus minimizing the footprint and assembly cost of the overall solution.

The RF6559 contains an integrated three stage power amplifier which provides

42dB of Gain and typical Power output of 28dBm. The RF6559 allows for Tx/Rx on

a single antenna via the 2 integrated SPDT switches. Tx filtering, built in power

detector and a two stage LNA which provides a typical 32dB of gain round out the

inside of this module. All the functionality ofthe RF6559 is packaged in a 28-pin,

6mm x 6mm laminate package with backside ground. Greatly minimizes next level

board space and allows for simplified integration.
