An embedded filtering passive (EFP) mixer is used to overcome transmitter power leakage in a receiver without the use of a SAW filter. The receiver IC exhibits more than + 60 dBm of Rx IIP2 , 2.4 dB Rx noise figure, and +77 dB of Triple Beat (TB) with 45 MHz offset transmit leakage at 900 MHz Rx frequency while consuming only 18 mA from a 2.1 V supply. Thanks to the embedded filtering passive mixer, the proposed receiver IC shows an additional 15 dB Tx rejection compared to a conventional… CONTINUE READING
