Analog Devices AD6411
The AD6411 provides the complete transmit and receive RF signal processing necessary to implement a digital wireless transceiver based on the Digital Enhanced Cordless Telecommunications (DECT) standard. The AD6411’s receive signal path consists of a mixer, IF amplifiers and PLL demodulator. The low noise, high intercept mixer is a development of the doubly-balanced Gilbert-Cell type.| Part No. | AD6411 |

DECT RF Transceiver AD6411 FUNCTIONAL BLOCK DIAGRAM PLL DEMODULATOR LNA RX DATA RSSI PLL VCO PA PFD TX DATA AD6411 CONTROL INTERFACE It has a nominal –16 dBm input-referred 1 dB compression point and a –8 dBm input referred third-order intercept. The limiter amplifier provides sufficient gain to drive the PLL demodulator, which provides selectable analog or sliced outputs. The RSSI output provides a voltage proportional to the receive signal strength.
