440-520MHz 7W 7.2V, 2 Stage Amp. For PORTABLE RADIO
DESCRIPTION
BLOCK DIAGRAM
The RA07M4452M is a 7-watt RF MOSFET Amplifier Module
2
3
for 7.2-volt portable radios that operate in the 440- to 520-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 2.5V (minimum), output power and drain
current increases substantially. The nominal output power
becomes available at 3V (typical) and 3.5V (maximum). At
VGG=3.5V, 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.

PRECAUTIONS, 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, Trichlorethylene)
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 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 soldering temperature must be lower than 260°C for a maximum of 10 seconds, or lower than 350°C for a maximum
of three seconds.
Ethyl Alcohol is recommend for removing flux. Trichlorethylene 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=7W, VDD=7.2V and Pin=50mW each stage transistor operating conditions are:

The channel temperatures of each stage transistor Tch = Tcase + (VDD x IDD - Pout + Pin) x R
are:
th(ch-case)
Tch1 = Tcase + (7.2V x 0.55A – 2W + 0.05W) x 4.5°C/W
Tch2 = Tcase + (7.2V x 1.85A – 7W + 2W) x 2.4°C/W
= Tcase + 9.0 °C
= Tcase + 20.0 °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=7W, the required thermal resistance Rth (case-air) = ( Tcase - Tair) / ( (Pout / hT ) - Pout
Pin ) of the heat sink, including the contact resistance, is:
+
Rth(case-air) = (90°C - 60°C) / (7W/40% – 7W + 0.05W) = 2.84 °C/W
When mounting the module with the thermal resistance of 2.84 °C/W, the channel temperature of each stage transistor
is:
Tch1 = Tair + 39.0 °C
Tch2 = Tair + 50.0 °C
The 175°C maximum rating for the channel temperature ensures application under derated conditions.

RA07M4452M
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=50W?
c) Is the source impedance ZG=50W?
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 mayoccur. 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.
