Notes:
1. In normal gain mode operation, Vbyp = 0V. Vc1, Vc2 and Vc3 are bias pins that are used to set the bias conditions to the 3 internal gain stages of
2. Typical quiescent current distribution with Vdd1 = Vdd2 = Vdd3 = Vbias = 5V, Vbyp = 0V, Vc = 2.1V is :
3. Low gain mode is enabled by setting Vbyp pin to 5V. This condition overrides the normal high gain mode operation and bypasses the first gain
4. Modulated signal measurements are made with Agilent 89600 VSA and Agilent E4438C signal generator with IEEE 802.16e option using the
5. Typical operating voltages and currents:
6. Vdd1/2/3 are shown as separate supplies with individual bypass capacitors. This yields the most stable configuration. If a common power supply

a. Idd1 = 50 mA
b. Idd2 = 180 mA
c. Idd3 = 270 mA
d. Ibias = 16.5mA

stage, regardless of the voltage at Vc1 pin.
following test conditions :
– Signal format: IEEE 802.16e OFDMA, ¾ rate FEC
– Modulation: 64-QAM
– Number of Subcarriers: 840
– Modulation bandwidth: 10 MHz
– Downlink ratio: 50%
Residual distortion of signal generator: (0.6-0.8)%. This distortion is not removed from the overall EVM data in the datasheet.
a. Normal gain mode: Vdd1 = Vdd2 = Vdd3 = Vbias = 5V. Vc = 2.1V. Vbyp = 0V. Iq(total) = 500 mA.
b. Low gain mode: Vdd1 = Vdd2 = Vdd3 = Vbias = 5V. Vc = 2.1V. Vbyp = 5V. Iq(total) = 500 mA.
line is used, proper broadband bypass decoupling is recommended to reduce common mode feedback through the supply line.
