2.5-GHz fully-integrated WiMAX transceiver IC for a compact, low-power-consumption RF module

A tri-band MIMO transceiver for mobile WiMAX with an image rejection ratio tunable SSB mixer

“…The demand for high-speed wireless data access has led to the development of the mobile WiMAX transceiver IC [1]. There are three major RF bands (2.3/2.5/3.5 GHz) used for mobile WiMAX.…”

6GHz active-inductor matched duplexer-less LNA/PA design incorporated with a bondwire-antenna

“…A few designs like [28] give the link budget and 13 operational range of the transceivers. Many designs, like [42], show excellent performance but do not show the duplexer design or give the power link budget between the transceivers. Designs like [43] show how to overcome PA leakage to the LNA via feedback cancellation of the leakage signal, but this approach requires several extra circuit blocks and has a higher power consumption.…”

“…Steps 1 to 7 are now repeated, and step 8 is ignored since it is not feasible to match the input of the second stage to R L of the first stage. 42…”
