(table 1) the recommended circuit configurations shown previously in this datasheet have the device operating with a 300 ma as the quiescent current (i cq ). this biasing level represents a tradeoff in terms of evm and efficiency. lowering i cq will improve upon the efficiency of the devi ce, but degrade the evm performance. measured data shown in the plots below represents the ap561 measured and configured for 2.4 ghz applications. it is expected that variation of the bias current for other frequency applications will produce similar performance results. table 1 : reduced current operation icq (ma) r2 ( ? ) v pd (v) pin_v pd (v) 300 330 5 2.85 280 300 5 2.81 260 280 5 2.78 240 261 5 2.76 220 249 5 2.73 200 232 5 2.71 evm vs. output average power vs. icq f=2.4 ghz 0 1 2 3 4 28 29 30 31 32 pout (dbm) evm (%) 200ma 220ma 240ma 260m a 280m a 300m a efficiency vs. output average power vs icq f=2.4 ghz, 8 10 12 14 16 18 28 29 30 31 32 pout (dbm) efficiency (%) 200ma 220ma 240ma 260ma 280ma 300ma
