Abstract :
An embedded filtering passive receiver mixer is used to overcome transmitter power leakage without the use of a SAW filter. The receiver IC exhibits more than +60 dBm of Rx IIP2, 2.4 dB Rx NF, and +77 dB of Triple Beat (TB) with 45 MHz transmit leakage at 900 MHz Rx frequency while consuming only 18 mA from a 2.1 V supply.
