AP513

AP513 Product Features • 1805 – 1880 MHz • 30 dB Gain • -64 dBc ACPR @ 28 dBm CDMA2k 7fa Power The Communications Edge TM Product Information DCS-band 8W HBT Amplifier Module Product Description The AP513 is a high dynamic range power amplifier in a RoHS-compliant flange-mount package. The multi-stage amplifier module has 30 dB gain, while being able to achieve high performance for DCS-band applications with +39 dBm of compressed 1dB power. The module has been internally optimized for linearity to provide -64 dBc ACPR at 28 dBm power for 7-carrier CDMA2000 applications. The AP513 uses a high reliability InGaP/GaAs HBT process technology and does not require any external matching components. The module operates off of a +12V supply and does not requiring any negative biasing voltages; an internal active bias allows the amplifier to maintain high linearity over temperature. It has the added feature of a +5V power down control pin. A low-cost metal housing allows the device to have a low thermal resistance and achieves over 100 years MTTF. All devices are 100% RF and DC tested.

The resistor – R7 – which sets the current draw for the amplifier is set at 0 Ω in this configuration. Increasing that value will decrease the quiescent and operating current of the amplifier module, as described on the next page. +12V GND +12V 10μF +5V DNP 0Ω 0Ω DNP 100pF DNP .01μF DNP RF IN 0Ω DNP DNP 6 .01μF DNP 100pF RF OUT 0Ω Notes: 1. Please note that for reliable operation, the evaluation board and mounting plate will have to be attached to a much larger heat sink during operation and in laboratory environments to dissipate the power consumed by the device. The use of a convection fan is also recommended in laboratory environments. Details of the mounting holes used in the WJ mounting plate are given on the last page of this datasheet. 2. The area around the module underneath the PCB should not contain any soldermask in order to maintain good RF grounding. 3. For proper and safe operation in the laboratory, the power-on sequencing should be followed: 1. Connect RF In and Out 2. Connect the voltages and ground pins as shown in the circuit. 3.

Because the device’s intended application is to be a power amplifier pre-driver or final stage output amplifier, the output RF power of the amplifier will help lower the overall power dissipation. In addition, the amplifier can be biased with different quiescent currents, so the calculation of the MTTF is custom to each application. The power dissipation of the device can be calculated with the following equation: Pdiss = Vcc * Icc – (Output RF Power – Input RF Power), Vcc = Operating supply voltage = 12V Icc = Operating current {The RF power is converted to Watts} While the maximum recommended case temperature on the datasheet is listed at 85 ˚C, it is suggested that customers maintain an MTTF above 1 million hours. This would convert to a derating curve for maximum case temperature vs. power dissipation as shown in the plot below. Maximum Recommended Case Temperature vs. Power Dissipation to maintain 1 million hours MTTF 90 Maximum Case Temperature (°C) To calculate the MTTF for the module, the junction temperature needs to be determined. This can be easily calculated with the module’s power dissipation, the thermal resistance value, and the case temperature of operation: Tj = Pdiss * Rth + Tcase Tj = Junction temperature Pdiss = Power dissipation (calculated from above) Rth = Thermal resistance = 4.5 ˚C/W Tcase = Case temperature of module’s heat sink From a numerical standpoint, the MTTF can be calculated using the Arrhenius equation: MTTF = A* e(Ea/k/Tj) A = Pre-exponential Factor = 6.087 x 10-11 hours Ea = Activation Energy = 1.39 eV k = Boltzmann’s Constant = 8.617 x 10-5 eV/ ºK Tj = Junction Temperature (ºK) = Tj (ºC) + 273 A graphical view of the MTTF can be shown in the plot below.
