BGA3023 - 1.2 GHz 20 dB gain CATV amplifier
1. Introduction
The BGA3023 customer evaluation board enables the user to evaluate the performance
of the medium power wideband CATV MMIC amplifier BGA3023.
The BGA3023 performance information is available in the BGA3023 datasheet.
This application note describes the evaluation board schematic and layout requirements
for using the BGA3023 as a CATV medium power amplifier between 40 MHz and 1200
MHz. The BGA3023 is fabricated in the BiCMOS process and packaged in a lead-free 8pin SOT786-2 package. The BGA3023 is surface-mounted on an evaluation board with
element matching and DC decoupling circuitry. The amplifier MMIC comprises a pushpull amplifier with internal bias network and operates over a frequency range of 40 MHz
to 1200 MHz with a supply voltage between 5 V and 8 V.

4. Application Information
For evaluation purposes an evaluation board is available. The evaluation circuit can be
seen in figure 1 and the corresponding PCB is shown in figure 2. Table 1 shows the bill
of materials.
4.1 Evaluation board circuit
Fig 1.
BGA3021 evaluation circuit
The power supply is applied on the Vcc pin of connector J3 and is applied to the
BGA3023 via chokes L2 and L3 which provides RF blocking to the supply line.
Capacitors C9, C10 and C11 are supply decoupling capacitors, where C4 and C5 are
decoupling capacitors for the control lines.
At the F-connector J1 the RF input signal is applied where capacitor C1 provides DCblocking, followed by C2 and L1 for input matching (Z = 75 Ω). The single ended
unbalanced 75 Ω signal is converted into a balanced signal for push pull configuration.
The balanced signal is applied to the input of BGA3023 at pin 1 and pin 4. Capacitor C3
provides DC-blocking. Capacitors C6 and C7 add extra capacitance to the output of
balun T1, which results in improved input matching.
At the output the amplified balanced signal are converted back into one 75 Ω single
ended signal by balun T2. Capacitors C14 and C15 add extra capacitance to the balun
for improved impedance matching. Capacitors C12 and C13 are DC-blocking capacitors.
Resistor R4 is a 0 Ω jumper and has no function other than passing the RF signal.
Resistor R3 provides a protection against damaging the internal crowbar due to
overshoot of the supply during switch on or switch off. This resistors needs to be in the
circuit to guarantee resistance against electrical overstress.

The Icc can be controlled via the IDC CTRL pin of connector J3. The high current mode
(350 mA) can be selected by leaving the IDC CTRL pin open or by applying 3.3V.The low
current mode can be selected by applying 0 V to the IDC CTRL pin.
The Temp pin on connector J3 gives access to an internal temperature sense diode
which can be used to verify proper thermal connection of the exposed die pad. The use
of this function is described in chapter 4.3
4.2 Choice of balun
The choice of balun is important when the maximum performance needs to be achieved,
especially on input and output return loss. Investigation showed that to get the best
output performance, balun type MABA-010245 should be used. This balun gives a good
output return loss and because of its low losses also give maximum P1dB, IP2 and IP3
levels.
However, balun type MABA-010245 does not give the best input return loss. Balun type
MABA-007159 with slightly more losses gives a much better input return loss. The extra
losses do not have any impact on the distortion values as it is placed at the input of the
device. The noise figure will slightly increase but is not a problem as the BGA3023 will be
used as final amplifier. For a system solution with low noise and more total gain the
BGA3018 can be used in front of the BGA3023.
Baluns also play a big role in the frequency coverage range. For frequencies lower than
40 MHz the BGA3023 can be made to work with the use of MABA-007532. Lab samples
show functionality between 5 MHz and 200 MHz with the use of MABA-007532 at the
input and output.

4.3 Temperature sense
Pin 2 of the BGA3023 gives access to a thermal diode which can be used to measure the
temperature increase between power-off state and power-on state. This can be very
helpful to check if the exposed die-pad has a good solder connection to the circuit board.
In case the solder connection has thermal voids a rapid increase in temperature can be
noticed.
A proposed circuit can be seen in fig 2.
During the whole test procedure a 1 mA current should be applied at pin 2. The Voltage
level Vtemp will represent the actual die temperature.

Temperature sense circuit
To check for any thermal solder voids the following procedure need to be followed:
Step 1: At power-off state and in room temperature measure Vtemp
Step 2: Power on the device
Step 3: Wait 1 second to let the device heat up.
Step 4: Measure Vtemp again
Step 5: Switch off power
The Vtemp Voltage difference between power-off and power-on will be about 200mV for
a device without thermal voids. When the Voltage difference is higher the thermal
connection is not good and performance cannot be guaranteed.

4.4 Evaluation board layout
Fig 3.
BGA3023 evaluation board layout
For optimum distortion performance it is important to have enough ground vias
underneath and around the MMICs ground pins. This lowers the inductance to the
ground plane. The evaluation board is made with two layer FR4 material.
