manufacturer: description:notes: 2. vdd = 7.0v, tc = 25c. part mounted on evaluation board with input and output matching to 50ω. 3. 9 channel forward link qpsk source; 1.23mbps modulation rate. cdma acpr1 is measured using the ratio of the average power within the 1.23mhz channel at band center to the average power within a 30khz bandwidth at an 885khz offset. minimum cdma output power is met with acpr1 > 36dbc. 4. oip3 specifications are achieved for power output levels of 27 and 30dbm per tone with tone spacing of 1.25mhz at band-center with adjusted supply and bias conditions of vdd = 6.5v and idqtotal = 625ma (see note 5). 5. vg1,2 and vg3 must be individually adjusted to achieve idq1,2 and idq3. a single vgg bias supply adjusted to achieve idqtotal = 625ma can be used with nearly equivalent performance. values for idq1,2 and idq3 shown have been optimized for cdma operation. idq1, 2 and idq3 (or idqtotal) can be adjusted to optimize the linearity of the amplifier for other modulation systems. |
