7 application information to ensure proper performance, refer to all related application notes on the anadigics web site: http://www.anadigics.com shutdown mode the power amplifer may be placed in a shutdown mode by applying logic low levels (see operating ranges table) to the v en , v mode1 and v mode2 voltages. bias modes the power amplifer may be placed in either low, medium or high bias modes by applying the appropriate logic level (see operating ranges table) table 6: bias control to the v mode voltages. the bias control table below lists the recommended modes of operation for various applications. three operating modes are recommended to optimize current consumption. high bias/high power operating mode is for p out levels > 16 dbm. at ~17dbm - 6.5 dbm, the pa should be mode switched to medium power mode. for p out levels < ~7.5 dbm, the pa can be switched to low power mode for even lower quiescent current consumption. figure 10: evaluation board schematic c3 330 pf c4 2.2 f ceramic rf in 1 6 7 10 8 5 4 3 v batt v mode1 rf out rf in gnd v cc v en cpl out v cc c1 0.01 f v batt v mode 1 v en cpl in v mode 2 29 v mode2 c5 2.2 f c2 0.01 f gnd at slug cpl in cpl out rf out c9 100 pf application p out levels bias mode v en v mode1 v mode2 v cc v b at t low power (low bias mode) ? +7.5 dbm low +1.8 v +1.8 v +1.8 v 3.1 - 4.35 v > 3.1 v med power (medium bias mode) > +6.5 dbm ?? +17 dbm low +1.8 v +1.8 v 0 v 3.1 - 4.35 v > 3.1 v high power (high bias mode) > +16 dbm high +1.8 v 0 v 0 v 3.1 - 4.35 v > 3.1 v shutdown - shutdown 0 v 0 v 0 v 3.1 - 4.35 v > 3.1 v data sheet - rev 2.3 03/2012 alt6708
