Silicon RF Power Semiconductors ELECTROSTATIC SENSITIVE DEVICE OBSERVE HANDLING PRECAUTIONS RA45H4047M RoHS Compliance, 400-470MHz 45W 12.5V, 3 Stage Amp. For MOBILE RADIO DESCRIPTION The RA45H4047M is a 45-watt RF MOSFET Amplifier Module for 12.5-volt mobile radios that operate in the 400- to 470-MHz range. The battery can be connected directly to the drain of the enhancement-mode MOSFET transistors. Without the gate voltage (VGG=0V), only a small leakage current flows into the drain and the RF input signal attenuates up to 60 dB. The output power and drain current increase as the gate voltage increases. With a gate voltage around 4V (minimum), output power and drain current increases substantially. The nominal output power becomes available at 4.5V (typical) and 5V (maximum). At VGG=5V, the typical gate current is 1 mA. This module is designed for non-linear FM modulation, but may also be used for linear modulation by setting the drain quiescent current with the gate voltage and controlling the output power with the input power.

RF Power Semiconductors ELECTROSTATIC SENSITIVE DEVICE OBSERVE HANDLING PRECAUTIONS RoHS COMPLIANCE RA45H4047M RECOMMENDATIONS and APPLICATION INFORMATION: Construction: This module consists of an alumina substrate soldered onto a copper flange. For mechanical protection, a plastic cap is attached with silicone. The MOSFET transistor chips are die bonded onto metal, wire bonded to the substrate, and coated with resin. Lines on the substrate (eventually inductors), chip capacitors, and resistors form the bias and matching circuits. Wire leads soldered onto the alumina substrate provide the DC and RF connection. Following conditions must be avoided: a) Bending forces on the alumina substrate (for example, by driving screws or from fast thermal changes) b) Mechanical stress on the wire leads (for example, by first soldering then driving screws or by thermal expansion) c) Defluxing solvents reacting with the resin coating on the MOSFET chips (for example, Trichloroethylene) d) Frequent on/off switching that causes thermal expansion of the resin e) ESD, surge, overvoltage in combination with load VSWR, and oscillation ESD: This MOSFET module is sensitive to ESD voltages down to 1000V. Appropriate ESD precautions are required. Mounting: Heat sink flatness must be less than 50 µm (a heat sink that is not flat or particles between module and heat sink may cause the ceramic substrate in the module to crack by bending forces, either immediately when driving screws or later when thermal expansion forces are added). A thermal compound between module and heat sink is recommended for low thermal contact resistance and to reduce the bending stress on the ceramic substrate caused by the temperature difference to the heat sink. The module must first be screwed to the heat sink, then the leads can be soldered to the printed circuit board. M3 screws are recommended with a tightening torque of 4.0 to 6.0 kgf-cm. Soldering and Defluxing: This module is designed for manual soldering. The leads must be soldered after the module is screwed onto the heat sink. The temperature of the lead (terminal) soldering should be lower than 350°C and shorter than 3 second. Ethyl Alcohol is recommend for removing flux. Trichloroethylene solvents must not be used (they may cause bubbles in the coating of the transistor chips which can lift off the bond wires). Thermal Design of the Heat Sink: At Pout=45W, VDD=12.5V and Pin=50mW each stage transistor operating conditions are: Pin Pout Rth(ch-case) IDD @ ηT=35% VDD Stage (W) (W) (V) (°C/W) (A) 1st 0.05 2.0 23.0 0.24 12.5 2nd 2.0 12.0 2.4 2.80 3rd 12.0 45.0 1.2 6.80 The channel temperatures of each stage transistor Tch = Tcase + (VDD x IDD - Pout + Pin) x Rth(ch-case) are: Tch1 = Tcase + (12.5V x 0.24A – 2.0W + 0.05W) x 23.0°C/W = Tcase + 24.2 °C Tch2 = Tcase + (12.5V x 2.80A - 12.0W + 2.0W) x 2.4°C/W = Tcase + 60.0 °C Tch3 = Tcase + (12.5V x 6.80A - 45.0W + 12.0W) x 1.2°C/W = Tcase + 62.4 °C For long-term reliability, it is best to keep the module case temperature (Tcase) below 90°C. For an ambient temperature Tair=60°C and Pout=45W, the required thermal resistance Rth (case-air) = ( Tcase - Tair) / ( (Pout / ηT ) Pout + Pin ) of the heat sink, including the contact resistance, is: Rth(case-air) = (90°C - 60°C) / (45W/35% – 45W + 0.05W) = 0.36 °C/W When mounting the module with the thermal resistance of 0.36 °C/W, the channel temperature of each stage transistor is: Tch1 = Tair + 54.2 °C Tch2 = Tair + 90.0 °C Tch3 = Tair + 92.4 °C The 175°C maximum rating for the channel temperature ensures application under derated conditions. RA45H4047M 25 Jun 2010 7/9 Silicon RF Power Semiconductors ELECTROSTATIC SENSITIVE DEVICE OBSERVE HANDLING PRECAUTIONS RoHS COMPLIANCE RA45H4047M Output Power Control: Depending on linearity, the following two methods are recommended to control the output power: a) Non-linear FM modulation: By the gate voltage (VGG). When the gate voltage is close to zero, the RF input signal is attenuated up to 60 dB and only a small leakage current flows from the battery into the drain. Around VGG=4V, the output power and drain current increases substantially. Around VGG=4.5V (typical) to VGG=5V (maximum), the nominal output power becomes available. b) Linear AM modulation: By RF input power Pin. The gate voltage is used to set the drain’s quiescent current for the required linearity. Oscillation: To test RF characteristics, this module is put on a fixture with two bias decoupling capacitors each on gate and drain, a 4.700 pF chip capacitor, located close to the module, and a 22 µF (or more) electrolytic capacitor. When an amplifier circuit around this module shows oscillation, the following may be checked: a) Do the bias decoupling capacitors have a low inductance pass to the case of the module? b) Is the load impedance ZL=50Ω? c) Is the source impedance ZG=50Ω?

PRECAUTION FOR THE USE OF MITSUBISHI SILICON RF POWER AMPLIFIER DEVICES: 1.The specifications of mention are not guarantee values in this data sheet. Please confirm additional details regarding operation of these products from the formal specification sheet. For copies of the formal specification sheets, please contact one of our sales offices. 2.RA series products (RF power amplifier modules) are designed for consumer mobile communication terminals and were not specifically designed for use in other applications. In particular, while these products are highly reliable for their designed purpose, they are not manufactured under a quality assurance testing protocol that is sufficient to guarantee the level of reliability typically deemed necessary for critical communications elements. Examples of critical communications elements would include transmitters for base station applications and fixed station applications that operate with long term continuous transmission and a higher on-off frequency during transmitting, especially for systems that may have a high impact to society. 3.RA series products use MOSFET semiconductor technology. They are sensitive to ESD voltage therefore appropriate ESD precautions are required. 4.In order to maximize reliability of the equipment, it is better to keep the devices temperature low. It is recommended to utilize a sufficient sized heat-sink in conjunction with other cooling methods as needed (fan, etc.) to keep the case temperature for RA series products lower than 60deg/C under standard conditions, and less than 90deg/C under extreme conditions. 5.RA series products are designed to operate into a nominal load impedance of 50 ohms. Under the condition of operating into a severe high load VSWR approaching an open or short, an over load condition could occur. In the worst case there is risk for burn out of the transistors and burning of other parts including the substrate in the module. 6.The formal specification includes a guarantee against parasitic oscillation under a specified maximum load mismatch condition. The inspection for parasitic oscillation is performed on a sample basis on our manufacturing line. It is recommended that verification of no parasitic oscillation be performed at the completed equipment level also. 7.For specific precautions regarding assembly of these products into the equipment, please refer to the supplementary items in the specification sheet. 8.Warranty for the product is void if the products protective cap (lid) is removed or if the product is modified in any way from it’s original form. 9.For additional “Safety first” in your circuit design and notes regarding the materials, please refer the last page of this data sheet. 10.
