2.5 GHz to 2.7 GHz WiMAX Power Amplifier ADL5571 FEATURES GENERAL DESCRIPTION Gain: 29 dB Operation from 2.5 GHz to 2.7 GHz EVM ≤ 3% with 16 QAM OFDMA @ POUT = 25 dBm (3.3 V, 2.6 GHz) @ POUT = 27 dBm (5 V, 2.6 GHz) Input matched to 50 Ω Power supply: 3.2 V to 5 V Quiescent current: 135 mA Power-added efficiency (PAE) 21% @ POUT = 25 dBm (3.3 V, 2.6 GHz) Multiple operating modes to reduce battery drain Standby mode: 9 mA Sleep mode: <1 μA The ADL5571 is a high linearity 2.5 GHz to 2.7 GHz power amplifier designed for WiMAX mobile terminals and CPEs using TDD operation at a duty cycle of 50% or lower. With a gain of 29 dB and an output compression point of 31 dBm, it can operate at an output power level up to 27 dBm while maintaining an EVM of ≤3% with a supply voltage of 5 V. PAE is 21% at POUT = 25 dBm with a 3.3 V supply voltage. The ADL5571 RF input is matched to provide an input return loss of better than 10 dB. The open-collector output is externally matched with a microstrip line and an external shunt capacitor. The ADL5571 operates over a supply voltage range from 3.2 V to 5 V with a current of 450 mA burst rms when delivering 25 dBm (3.3 V supply). A standby mode is available that reduces the quiescent current to 9 mA, which is useful when a TDD terminal is receiving data. APPLICATIONS WiMAX mobile terminals and CPEs The ADL5571 is fabricated in a GaAs HBT process and is packaged in a 4 mm × 4 mm, 16-lead, Pb-free, RoHS-compliant LFCSP that uses an exposed paddle for excellent thermal impedance. It operates from −40°C to +85°C. FUNCTIONAL BLOCK DIAGRAM VCC1 VCC2 ADL5571 STBY IM1 FIRST STAGE BIAS_1 IM2 SECOND STAGE BIAS_2 VREG IM3 THIRD STAGE RFOUT OM BIAS_3 CFLT 06956-001 RFIN Figure 1.

VCC1 is decoupled with Capacitor C7, whereas VCC2 uses a tank circuit to prevent RF signals from propagating on the dc lines. RF Input Interface 2.7nH 6 RFIN During normal transmit mode, the STBY pin is biased low (0 V). However, during receive mode, the pin can be biased high (2.5 V) to shift the device into standby mode, which reduces current consumption to 9 mA. VREG Enable During normal transmit, the VREG pin is biased to 2.85 V and draws 9 mA of current. When the VREG pin is low (0 V), the device suspends itself into sleep mode (irrespective of supply biasing). In this mode, the device draws less than 1 μA of current. 06956-004 The RFIN pin is the port for the RF input signal to the power amplifier.

EVM vs. POUT Performance at VCC = 3.3 V and 64 QAM OFDMA Signal The efficiency of the ADL5571 is defined on the current that it draws during the data burst of an 802.16e OFDMA signal. In typical test setup, the average rms current, IAVG, is measured. However, IAVG = Duty Cycle (in decimal) × IBURST + (1 − Duty Cycle [in decimal]) × IDEFAULT 32 where: IBURST is the rms current during the data burst of an OFDMA signal. IDEFAULT can be the quiescent current drawn when there is no data burst and the device remains biased, the sleep current (<1 μA) if the device is defaulted to sleep mode, or the standby current. 31 30 29 28 For example, in a 31% duty cycle 802.16e OFDMA signal, the burst current is calculated by rearranging the previous equation to get 27 26 2500 2520 2540 2560 2580 2600 2620 2640 2660 2680 2700 FREQUENCY (MHz) Figure 23.
