Manufacturer:VISHAY 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. |
