MITSUBISHI RF MOSFET MODULE ELECTROSTATIC SENSITIVE DEVICE OBSERVE HANDLING PRECAUTIONS RA45H7687M1 BLOCK DIAGRAM 2 3 RoHS Compliance, 764-870MHz 45W 12.8V, 2 Stage Amp. For MOBILE RADIO DESCRIPTION The RA45H7687M1 is a 45-watt RF MOSFET Amplifier Module for 12.8-volt mobile radios that operate in the 764- to 870-MHz range. The battery can be connected directly to the drain of the enhancement-mode MOSFET transistors. Without the gate voltage 1 and the gate voltage 2(VGG1=VGG2=0V), only a small leakage current flows into the drain and the nominal output signal (Pout=45W) attenuates up to 60 dB. When fixed i.e. 3.4V, is supplied to the gate voltage 1, the output power and the drain current increase as the gate voltage 2 increases. The output power and the drain current increase substantially with the gate voltage 2 around 0V (minimum) under the condition when the gate voltage 1 is kept in 3.4V. The nominal output power becomes available at the state that VGG2 is 4V (typical) and 5V (maximum). At this point, VGG1 has to be kept in 3.4V. At VGG1=3.4V & VGG2=5V, the typical gate currents are 0.4mA. 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 voltages and controlling the output power with the input power.

RA45H7687M1 MITSUBISHI ELECTRIC 6/9 29 Feb 2008 th ELECTROSTATIC SENSITIVE DEVICE OBSERVE HANDLING PRECAUTIONS MITSUBISHI RF POWER MODULE RoHS COMPLIANCE RA45H7687M1 PRECAUTIONS, RECOMMENDATIONS, and APPLICATION INFORMATION: Construction: This module consists of a glass-epoxy substrate soldered onto a copper flange. For mechanical protection, a metal cap is attached (which makes the improvement of RF radiation easy). 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 glass-epoxy substrate provide the DC and RF connection. Following conditions must be avoided: a) Bending forces on the glass-epoxy 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: A thermal compound between module and heat sink is recommended for low thermal contact resistance. 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 0.4 to 0.6 Nm. 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 350C 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=12.8V and Pin=50mW each stage transistor operating conditions are: Pin Pout Rth(ch-case) IDD @ T=33% VDD Stage (W) (W) (V) (C/W) (A) 1st 0.05 3.0 3.5 0.62 12.8 2nd 3.0 45.0 0.6 9.96 The channel temperatures of each stage transistor Tch = Tcase + (VDD x IDD - Pout + Pin) x Rth(ch-case) are: Tch1 = Tcase + (12.8V x 0.62A - 3.0W + 0.05W) x 3.5C/W = Tcase + 17.5 C Tch2 = Tcase + (12.8V x 9.96A - 45.0W + 3.0W) x 0.6C/W = Tcase + 51.3 C For long-term reliability, it is best to keep the module case temperature (Tcase) below 90C. For an ambient temperature Tair=60C and Pout=45W, the required thermal resistance Rth (case-air) = ( Tcase - Tair) / ( (Pout / T ) Pout + Pin ) of the heat sink, including the contact resistance, is: Rth(case-air) = (90C - 60C) / (45W/33% - 45W + 0.05W) = 0.33 C/W When mounting the module with the thermal resistance of 0.33 C/W, the channel temperature of each stage transistor is: Tch1 = Tair + 47.5 C Tch2 = Tair + 81.3 C The 175C maximum rating for the channel temperature ensures application under derated conditions. RA45H7687M1 MITSUBISHI ELECTRIC 7/9 29 Feb 2008 th ELECTROSTATIC SENSITIVE DEVICE OBSERVE HANDLING PRECAUTIONS MITSUBISHI RF POWER MODULE RoHS COMPLIANCE RA45H7687M1 Output Power Control: Depending on linearity, the following three methods are recommended to control the output power: a) Non-linear FM modulation at high power operating: By the gate voltages (VGG1 and VGG2). When the gate voltages are close to zero, the nominal output signal (Pout=45W) is attenuated up to 60 dB and only a small leakage current flows from the battery into the drain. (On the following, V GG1 has to be kept in 3.4V.) Around VGG2=0V(minimum), the output power and drain current increases substantially. Around VGG2=4V (typical) to VGG2=5V (maximum), the nominal output power becomes available. b) Linear AM modulation: By RF input power Pin. (On the following, V GG1 has to be kept in 3.4V.) VGG2 is used to set the drain's quiescent current for the required linearity. Load condition of Output terminal: This module suppose to use on the condition that load impedance is 50ohm. On the over load condition,this module run into the short mode in the worst case and the module involve the risk of burn out and smoking of parts including the substrate in the module. 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 F (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=50? c) Is the source impedance ZG=50? Frequent on/off switching: In base stations, frequent on/off switching can cause thermal expansion of the resin that coats the transistor chips and can result in reduced or no output power. The bond wires in the resin will break after long-term thermally induced mechanical stress. Quality: Mitsubishi Electric is not liable for failures resulting from base station operation time or operating conditions exceeding those of mobile radios. This module technology results from more than 20 years of experience, field proven in tens of millions of mobile radios. Currently, most returned modules show failures such as ESD, substrate crack, and transistor burnout, which are caused by improper handling or exceeding recommended operating conditions. Few degradation failures are found. Keep safety first in your circuit designs! Mitsubishi Electric Corporation puts the maximum effort into making semiconductor products better and more reliable, but there is always the possibility that trouble may occur. Trouble with semiconductors may lead to personal injury, fire or property damage. Remember to give due consideration to safety when making your circuit designs, with appropriate measures such as (i) placement of substitutive, auxiliary circuits, (ii) use of non-flammable material, or (iii) prevention against any malfunction or mishap.
