Functional Block Diagram
Product Description The RF6505 integrates a complete solution in a single Front End Module (FEM) for WiFi and ZigBee applications in the 2.4GHz to 2.5GHz band. This FEM integrates a balun, TX/RX switch, power amplifier, harmonic filter, DP2T switch, and low noise amplifier with bypass mode. It provides a single balanced TDD access for Rx and Tx paths along with two ports on the output for connecting a diversity solution or a test port. The device is provided in a 3.5mm x 3.5mm x 0.5mm, 20-pin QFN package.

Description Differential RF input for PA (TX_Mode) and output for LNA (RX_Mode) internally matched to 100Ω. Ground. Differential RF input for PA (TX_Mode) and output for LNA (RX_Mode) internally matched to 100Ω. Voltage supply for VCC Bias. An external 0.1uF capacitor might be needed for low frequency decoupling. Enable voltage pin for the PA and switch. See logic table for operation. Provides and output voltage proprtional to the output RF level. Ground. Voltage supply for the first and second stages of the PA. An external 1uF capacitor might be needed for low frequency decoupling. This pin is connected internally (C/I) to Pin 8 therfore this pin should not be grounded. This pin should be left open. Voltage supply for the third stage of the PA. An external 1uF capacitor might be needed for low frequency decoupling No connect. Ground. This is a common port (antenna). It is matched to 50Ω and DC block is provided internally. Ground. This is a common port (antenna). It is matched to 50Ω and DC block is provided internally. Control pin for antenna select. See logic table for operation. Control pin for antenna select. See logic table for operation. Voltage supply. An external 1uF capacitor might be needed for low frequency decoupling. LNA enable pin for selecting between High gain mode and Bypass mode. Enable voltage pin for the Receive mode and switch. See logic table for operation.
