Notes:
2. V
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. VG1 and VG2 must be individually adjusted to achieve IDQ1 and IDQ2. A single VGG bias supply adjusted to achieve IDQTOTAL = 550mA can be used with
nearly equivalent performance. Values for IDQ1 and IDQ2 shown have been optimized for CDMA operation. IDQ1 and IDQ2 (or IDQTOTAL) can be adjusted to
optimize the linearity of the amplifier for other modulation systems.
5. OIP3 specifications are achieved for power output levels of 27 and 30 dBm per tone with tone spacing of 1.25MHz at bandcenter.
= 7.0V, T
= 25°C. Part mounted on evaluation board with input and output matching to 50
.
