MGA-43228 (2.3–2.5) GHz 29dBm High Linearity Wireless Data Power Amplifier Data Sheet Description Features Avago Technologies’ MGA-43228 is a power amplifier for use in the (2.3-2.5)GHz band. High linear output power at 5V is achieved through the use of Avago Technologies’ proprietary 0.25um GaAs Enhancement-mode pHEMT process. It is housed in a miniature 5.0mm x 5.0mm x 0.85mm 28-lead QFN package. It also includes shutdown and switchable gain functions. A detector is also included on-chip. The compact footprint coupled with high gain and high efficiency make the MGA-43228 an ideal choice as a power amplifier for IEEE 802.16 (WiMAX) and WLL applications. High gain: 38.5dB High linearity performance: 29.2dBm at 5V supply (2.5% EVM, 64-QAM ¾ FEC rate OFDMA, 10MHz bandwidth) High efficiency: 16.1% Built-in detector and shutdown switches Switchable gain: 23.6dB attenuation using one single CMOS compatible switch pin ETSI spectral mask compliant at 29dBm output power GaAs E-pHEMT Technology[1] Low cost small package size: 5.0 x 5.0 x 0.85 mm3 Component Image MSL-2a and lead-free Usable at 3.3V supply for lower supply voltage applications Vdd3 Vdd3 Vdd3 Vdd1 Gnd Vdd2 5.0 x 5.0 x 0.85 mm3 28-lead QFN Package (Top View) Specifications 43228 YYWW XXXX RFout RFout RFout Gnd RFin 38.5 dB Gain Vdet Vbias Vc1 Vc2 Vc3 Vbyp Notes: Package marking provides orientation and identification ”43228” = Device part number ”YYWW” = Year and work week ”XXXX” = Assembly lot number Vdd2 29.2 dBm Linear Pout (2.5% EVM) 16.1% PAE @ Linear Pout 2.6V Vdet @ Linear Pout 23.6 dB Switchable Gain Attenuation 25A Shutdown Current Applications Functional Block Diagram Vdd1 2.4GHz; Vdd = Vbias = 5.0V, Vc = 2.1V (R2 = 1.2k, R3 = 300, R4 = 1.2k as shown in Figure 36), Iqtotal = 500mA (typ), IEEE 802.16e 64-QAM OFDMA, ¾ FEC rate High linearity amplifier for IEEE 802.16 fixed terminal amplifier Vdd3 WLL amplifier RFin RFout Gain switch and bias circuitry Vbyp Vc1 Vc2 Vc3 Vbias Vdet Note: 1.

Application schematic in demonstration board 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 the PA. 2. Typical quiescent current distribution with Vdd1 = Vdd2 = Vdd3 = Vbias = 5V, Vbyp = 0V, Vc = 2.1V is : a. Idd1 = 50 mA b. Idd2 = 180 mA c. Idd3 = 270 mA d. Ibias = 16.5mA (Note: Vc supplied through Vc2 pin on demonstration board with R2 = 1.2k , R3 = 300 and R4 = 1.2k) 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 stage, regardless of the voltage at Vc1 pin. 4. Modulated signal measurements are made with Agilent 89600 VSA and Agilent E4438C signal generator with IEEE 802.16e option using the 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. 5. Typical operating voltages and currents: 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. 6. Vdd1/2/3 are shown as separate supplies with individual bypass capacitors. This yields the most stable configuration. If a common power supply line is used, proper broadband bypass decoupling is recommended to reduce common mode feedback through the supply line. 15 PCB Land Pattern and Stencil Outline 0.250 0.250 ø 0.300 C'fer 0.300 X 45° 0.300 0.675 1.125 3.600 0.250 1.520 0.250 0.600 3.240 3.600 Stencil Outline PCB Land Pattern (Top View) 0.250 0.250 C'fer 0.300 X 45° 0.675 1.125 1.520 3.240 Combined PCB Land Pattern and Stencil Outline 16 0.360 (All dimensions in mm) 0.360 QFN 5.0 x 5.0 x 0.85mm3 28-Lead Package Dimensions Pin 1 5.00±0.05 0.203 Ref 43228 YYWW XXXX 5.00±0.05 0.000-0.05 0.85±0.05 Side View Top View PIN #1 IDENTIFICATION CHAMFER 0.400 X 45° 3.60±0.050 Exp.DAP 0.40±0.050 0.50 Bsc 3.60±0.050 Exp.DAP 0.25±0.050 3.00 Ref.
