Description
Interface Schematic
Internally connected to the ground slug.
Ground connection for the driver stage. To minimize the noise power at the
output, it is recommended to connect this pin with a trace of about 40mil
to the ground plane. This will slightly reduce the small signal gain, and
lower the noise power. It is important for stability that this pin have it’s own
vias to the ground plane, minimizing common inductance.
RF Input. This is a 50 input, but the actual impedance depends on the
interstage matching network connected to pin 5. An external DC blocking
capacitor is required if this port is connected to a DC path to ground or a

2.6V for +35dBm RF output power. The maximum power that can be
achieved depends on the actual output matching; see the application information for more details. The maximum current into this pin is 5mA when

RF2173
Theory of Operation and Application Information
The RF2173 is a three-stage device with 32 dB gain at full power. Therefore, the drive required to fully saturate the output is
+3dBm. Based upon HBT (Heterojunction Bipolar Transistor) technology, the part requires only a single positive 3V supply to
operate to full specification. Power control is provided through a single pin interface, with a separate Power Down control pin.
The final stage ground is achieved through the large pad in the middle of the backside of the package. First and second stage
grounds are brought out through separate ground pins for isolation from the output. These grounds should be connected
directly with vias to the PCB ground plane, and not connected with the output ground to form a so called “local ground plane”
on the top layer of the PCB. The output is brought out through the wide output pad, and forms the RF output signal path.
SI
GN
S
The amplifier operates in near Class C bias mode. The final stage is "deep AB", meaning the quiescent current is very low. As
the RF drive is increased, the final stage self-biases, causing the bias point to shift up and, at full power, draws about 2000mA.
The optimum load for the output stage is approximately 1.2. This is the load at the output collector, and is created by the
series inductance formed by the output bond wires, vias, and microstrip, and 2 shunt capacitors external to the part. The optimum load impedance at the RF Output pad is 1.5-j1.7 With this match, a 50 terminal impedance is achieved. The input is
internally matched to 50 with just a blocking capacitor needed. This data sheet defines the configuration for GSM operation.
DE
The input is DC coupled; thus, a blocking cap must be inserted in series. Also, the first stage bias may be adjusted by a resistive divider with high value resistors on this pin to VPC and ground. For nominal operation, however, no external adjustment is
necessary as internal resistors set the bias point optimally.
W
VCC1 and VCC2 provide supply voltage to the first and second stage, as well as provides some frequency selectivity to tune to
the operating band. Essentially, the bias is fed to this pin through a short microstrip. A bypass capacitor sets the inductance
seen by the part, so placement of the bypass cap can affect the frequency of the gain peak. This supply should be bypassed
individually with 100pF capacitors before being combined with VCC for the output stage to prevent feedback and oscillations.
NE
The RF OUT pin provides the output power. Bias for the final stage is fed to this output line, and the feed must be capable of
supporting the approximately 2A of current required. Care should be taken to keep the losses low in the bias feed and output
components. A narrow microstrip line is recommended because DC losses in a bias choke will degrade efficiency and power.
FO
R
While the part is safe under CW operation, maximum power and reliability will be achieved under pulsed conditions. The data
shown in this data sheet is based on a 12.5% duty cycle and a 600s pulse, unless specified otherwise.
NO
T
The part will operate over a 3.0V to 5.0V range. Under nominal conditions, the power at 3.5V will be greater than +34.5dBm at
+90°C. As the voltage is increased, however, the output power will increase. Thus, in a system design, the ALC (Automatic
Level Control) Loop will back down the power to the desired level. This must occur during operation, or the device may be damaged from too much power dissipation. At 5.0V, over +38dBm may be produced; however, this level of power is not recommended, and can cause damage to the device.
The HBT breakdown voltage is >20V, so there are no issue with overvoltage. However, under worst-case conditions, with the RF
drive at full power during transmit, and the output VSWR extremely high, a low load impedance at the collector of the output
transistors can cause currents much higher than normal. Due to the bipolar nature of the devices, there is no limitation on the
amount of current de device will sink, and the safe current densities could be exceeded.
High current conditions are potentially dangerous to any RF device. High currents lead to high channel temperatures and may
force early failures. The RF2173 includes temperature compensation circuits in the bias network to stabilize the RF transistors,
thus limiting the current through the amplifier and protecting the devices from damage. The same mechanism works to compensate the currents due to ambient temperature variations.
To avoid excessively high currents it is important to control the VAPC when operating at supply voltages higher than 4.0V, such
that the maximum output power is not exceeded.

A buffer amplifier is recommended because the current into the
VAPC changes with voltage. As an alternative, the voltage may be
monitored with an oscilloscope.
Notes about testing the RF2173
NO
T
The test setup shown above includes two attenuators. The 3dB pad at the input is to minimize the effects that the switching
of the input impedance of the PA has on the signal generator. When VAPC is switched quickly, the resulting input impedance
change can cause the signal generator to vary its output signal, either in output level or in frequency. Instead of an attenuator
an isolator may also be used. The attenuator at the output is to prevent damage to the spectrum analyzer, and should be able
to handle the power.
It is important not to exceed the rated supply current and output power. When testing the device at higher than nominal supply voltage, the VAPC should be adjusted to avoid the output power exceeding +36dBm. During load-pull testing at the output
it is important to monitor the forward power through a directional coupler. The forward power should not exceed +36dBm,
and VAPC needs to be adjusted accordingly. This simulates the behavior for the power control loop in this respect. To avoid
damage, it is recommended to set the power supply to limiting the current during the burst, not to exceed the maximum current rating.

PCB Solder Mask Pattern
Liquid Photo-Imageable (LPI) solder mask is recommended. The solder mask footprint will match what is shown for the PCB
Metal Land Pattern with a 3mil expansion to accommodate solder mask registration clearance around all pads. The centergrounding pad shall also have a solder mask clearance. Expansion of the pads to create solder mask clearance can be provided in the master data or requested from the PCB fabrication supplier.

Thermal Pad and Via Design
The PCB land pattern has been designed with a thermal pad that matches the exposed die paddle size on the bottom of the
device.
Thermal vias are required in the PCB layout to effectively conduct heat away from the package. The via pattern shown has been
designed to address thermal, power dissipation and electrical requirements of the device as well as accommodating routing
strategies.

The via pattern used for the RFMD qualification is based on thru-hole vias with 0.203mm to 0.330mm finished hole size on a
0.5mm to 1.2mm grid pattern with 0.025mm plating on via walls. If micro vias are used in a design, it is suggested that the
quantity of vias be increased by a 4:1 ratio to achieve similar results.
Figure 3. shows the via pattern used for the RFMD qualification design.
