CC = 120 mA
This device is packaged in a 4mm x 4mm, 24ꢀpin Thin
QFN with 50 ohm differential RF input and 50 ohm
single ended RF output impedances for ease of
integration into the signalꢀpath.
Up to +105 °C TCASE operating temperature

OMPETITIVE
ADVANTAGE
In typical Base Stations, RF Amplifiers are used in the
TX traffic paths to drive the transmit power amplifier.
The F1423 TX Amplifier offers very high reliability due
to its construction using silicon die in a QFN package.
The F1423 includes a broadband differential input to
accept ACꢀcoupled signals directly from a balanced
modulator or RF DAC architecture.

Note 1: The RFIN+ and RFINꢀ pins connect to an internal balun that presents a very low impedance to ground.
Stresses above those listed above may cause permanent damage to the device. Functional operation of the device at
these or any other conditions above those indicated in the operational section of this specification is not implied.
Exposure to absolute maximum rating conditions for extended periods may affect device reliability.

Note 1: Though device linearity is specified over the range from 700 MHz to 2700 MHz, gain flatness up to 3000 MHz
is specified in the highꢀband and broadband tables to account for extended DPD bandwidth requirements.
Note 2: To optimize RF performance, a different output match will be used for each of the 4 RF bands listed (see
Table 2). In addition, different value amplifier bias resistors will be used to optimize performance in each of
the 4 bands.

EVKIT traces, connectors, and transformer losses are de-embedded.
S-parameters (S11, S21, S12, and S22) measured using a de-embedded Differential Board EVKit
and the inputs are mathematically combined using an ideal 1:1 (50 ꢁ : 50 ꢁ) transformer to
produce the 2 port S-parameters.

Amplitude and phase imbalances measures RFIN+ to RFOUT and compares to RFIN- to RFOUT.
Phase imbalance is the deviation from an ideal 180 degrees.
OIP3, Output P1dB and Noise Figure measured using a Transformer Board EVKit.
Note: The use of the external transformer T1 is included for simple 2 port evaluation purposes.
At some frequencies the external transformer interacts with the onꢀchip balun affecting the gain and noise
figure flatness responses. These interactions have been removed from the noise figure TOCs.

F1423
A
PPLICATIONS NFORMATION
I
The F1423 has been optimized for use in high performance RF applications from 600 MHz to 3000 MHz.
STBY
The STBY control pin allows for power saving when the device is not in use. Setting the STBY pin to a logic
low, or leaving the pin open, will put the device in normal operation mode. The STBY pin has an internal
1 Meg ohm resistor to ground. Applying a logic high to this pin will put the part in standby mode. Voltage
should not be applied to the STBY pin without VCC present.
Band_Sel
The Band_Sel control pin can be used to adjust the current in the device for Mid Band, High Band, and Wide
Band frequency applications. This is done by grounding the Band_Sel pin. Internally there is a 1.5 Meg ohm
pullꢀup resistor. Voltage should not be applied to the Band_Sel pin without VCC present.
RBias1 and RBias2
RBIAS1 (pin 14) and RBIAS2 (pin 15) use a single external resistor to ground on each pin to set the DC
current in the device and to optimize the linearity performance of the amplifier stage. The resistor values in
Table 2 can be used as a guide for the RF band of interest. By decreasing the resistor value to ground on the
RBIAS1 pin will increase the DC current in the amplifier stage. The resistor to ground on RBIAS2 is used to
optimize the linearity performance in conjunction with the resistor on RBIAS1.
Amplifier Stability
To ensure unconditional stability the value of R1 should be set to 510 Ohms. This will reduce the RF Gain,
OIP3, and OP1dB by approx 0.4 dB. Additionally, shunt resistors to ground of approximately 1k ohm should be
connected from pin 1 to ground and pin 3 to ground. This will stabilize the circuit due to common mode
source impedances. The installed 1k resistor will add 0.1 dB degradation to the Gain and Noise Figure. The
1k ohm will also dampen any common mode amplitude and phase interactions from the differential source
impedance and the F1423 differential input impedance.
Power Supplies
A common VCC power supply should be used for all pins requiring DC power. All supply pins should be
bypassed with external capacitors to minimize noise and fast transients. Supply noise can degrade noise figure
and fast transients can trigger ESD clamps and cause them to fail. Supply voltage change or transients should
have a slew rate smaller than 1 V / 20 µs. In addition, all control pins should remain at 0 V (+/ꢀ0.3 V) while the
supply voltage ramps or while it returns to zero.
Control Pin Interface
If control signal integrity is a concern and clean signals cannot be guaranteed due to overshoot, undershoot,
ringing, etc., the following circuit at the input of each control pin is recommended. This applies to all control
pins 11 and 13. Note the recommended resistor and capacitor values do not necessarily match the EV kit BOM
for the case of poor control signal integrity.

Note 1: When using an external transformer for evaluation, a common mode resonance interaction can occur with the
onꢀchip balun. Resistors R13 and R14 will dampen the resonance but affects the Gain and NF by approx 0.2dB.

PERATION
The F1423 EVkits (single ended and differential) have a number of control features available.
STBY (2 pin Header J5)
Twoꢀpin header J5 can be used to set the part for operational or standby mode. Leaving the two J5
pins unconnected will place it in the operational mode. Connecting the two J5 pins together will pull
up the STBY pin to Vcc through R4 and place the part into the standby mode.
Band_Sel (2 pin Header J4)
Twoꢀpin header J4 can be used to set the part for best operational performance in different RF bands.
Based on Table 2 above the LowꢀBand performance is best with these two J4 pins left open while the
other bands typically have these two pins shorted together.
RF Band Biasing (RBIAS1, RBIAS2, Band_Sel)
Below are 4 settings showing the recommended J4, J7, and J8 jumper connections for best linearity
performance in the different RF bands. The jumpers (shown in red below) select the RBIAS1 and
RBIAS2 resistor values along with the Band_Sel setting (see Table 2 above). Never have two shunts
installed at the same time on header J7 since this may produce excessive bias current and damage
the part.
