A 1.99 preliminary Data Sheet • SKY65124 Theory of Operation The SKY65124 is comprised of two amplifier stages. The matching circuits for the input stage, inter-stage, and output stage are contained within the device. An on-chip active bias circuit is included within the device for both input and output stages providing for excellent gain tracking over temperature and voltage variations. The SKY65124 is internally matched for optimum linearity and efficiency. The input and output stages are independently supplied using the VCC1 and VCC2 supply lines, pins 13 and 11, respectively. The bias reference voltages for stages 1 and 2 are supplied using common lines VREF1 and VREF2 (pins 6 and 7) line. The DC control voltage that sets the bias to stages 1 and 2 is supplied via VC_BIAS, pin 4. Application Circuit Notes Center Ground. It is extremely important that the device paddle be sufficiently grounded for both thermal and stability reasons. Multiple small vias are acceptable and will work well under th edevice if solder migration is an issue. Ground (Pins 1, 2, 3, 8, 10, 17, 19, 20). Attach all ground pins to the RF ground plane with the largest diameter and lowest inductance via that the layout will allow. Multiple small vias are also acceptable and will work well under the device if solder migration is an issue. VC_BIAS (Pin 4). VC_BIAS is the bias supply voltage for stages 1 and 2. Typically set to 5 V. VREF1 (Pin 6). Bias reference voltage for amplifier stage 1. VREF1 should be operated over the same voltage range as VCC, with a nominal voltage of 5 V. VREF2 (Pin 7). Bias reference voltage for amplifier stage 2. VREF1 should be operated over the same voltage range as VCC, with a nominal voltage of 5 V. RF_OUT (Pin 9). Amplifier RF Output Pin. ZO = 50 W. The module includes an onboard internal DC blocking capacitor. All impedance matching is provided internal to the module. VCC2 (Pin 11). Supply voltage for the output (final) stage collector bias (typically 5 V). Bypassing of VCC2 is accomplished with C10, C11 and C12 and should be placed in the approximate location shown on the evaluation board, but placement is not critical. VCC1 (Pin 13). Supply voltage for the first stage collector bias (typically 5 V). Bypassing of VCC1 is accomplished with C6, C7 and C8 and should be placed in the approximate location shown on the evaluation board, but placement is not critical. RF_IN (Pin 16). Amplifier RF Input Pin. ZO = 50 W. The module includes an onboard internal DC blocking capacitor. All impedance matching is provided internal to the module. No Connect (Pins 5, 12, 14, 15, 18). The pins are open and may or may not be connected to ground. Skyworks Solutions, Inc. • Phone [781] 376-3000 • Fax [781] 376-3100 • [email protected] • www.skyworksinc.com 200996 Rev.

Instructions on the shipping container label regarding exposure to moisture after the container seal is broken must be followed. Otherwise, problems related to moisture absorption may occur when the part is subjected to high temperature during solder assembly. The SKY65124 is a static-sensitive electronic device. Do not operate or store near strong electrostatic fields. Take proper ESD precautions.

Evaluation Board Description The Skyworks SKY65124 Evaluation Board is used to test the performance of the SKY65124 power amplifier module. The following design considerations are general in nature and must be followed regardless of final use or configuration. 1. Paths to ground should be made as short as possible. 2. The ground pad of the SKY65124 power amplifier module has special electrical and thermal grounding requirements. This pad is the main thermal conduit for heat dissipation. Since the circuit board acts as the heat sink, it must shunt as much heat as possible from the amplifiers. As such, design the connection to the ground pad to dissipate the maximum wattage produced to the circuit. Multiple vias to the grounding layer are required. RF_Out Evaluation Board Test Procedure Step 4. Apply RF signal data -10 dBm level and observe that the output level is approximately 14 dBm or the gain of the device is approximately 24 dB. NOTE: It is important that the VCC1 and VCC2 voltage source be adjusted such that 5 V is measured at the board. The high collector currents will drop the collector voltage significantly if long leads are used. Adjust the bias voltage to compensate. Recommended Solder Reflow Profiles Refer to the “Recommended Solder Reflow Profile” Application Note. Tape and Reel Information Refer to the “Discrete Devices and IC Switch/Attenuators Tape and Reel Package Orientation” Application Note. NOTE: J unction temperature (TJ) of the device increases with a poor connection to the slug and ground. This reduces the lifetime of the device.
