RF6504

3.3V TO 4.0V, 433MHz TO 470MHz

TRANSMIT/RECEIVE FRONT END MODULE

RF6504 is a front end module (FEM) intended for 433MHz to 470MHz AMI/AMR

systems. This module provides separate ports for Rx and Tx paths. The Tx section

provides a PA with nominal output power of 30dBm and gain of 15dB. The Rx is a

pass through. Both are combined to a single antenna port with a SP2T switch. The

device is provided in a 5.5mm x 5.0mm, 28-pin package.
