Microwave Monolithic Integrated Circuits (MMICs), comprised of Gallium Arsenide (GaAs) and Si CMOS, contain all active circuitry in the module, which includes on-board bias circuitry as well as input and interstage matching circuits. The input and output match is realized off-chip within the module package to optimize efficiency and high power performance (P3 dB_SAT ≅ 35.6 dBm) into a 50 Ω load. Primary bias to the SKY65146 can be supplied directly from a single cell lithium-ion or other suitable battery with a nominal output of 3.5 V. No external supply side switch is needed as typical “off” leakage is a few microamperes with full primary voltage supplied from the battery. The ICs are manufactured on an advanced InGaP HBT process and on a silicon CMOS process, providing for all positive voltage DC supply operation while maintaining high efficiency and good linearity. The module can operate over the temperature range of -40 ˚C to 85 ˚C. A populated evaluation board is available upon request. NEW Skyworks offers lead (Pb)-free, RoHS (Restriction of Hazardous Substances)-compliant packaging.

A DATA SHEET • SKY65146 Application Circuit Notes Package and Handling Information 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 the device if solder migration is an issue. Since the device package is sensitive to moisture absorption, it is baked and vacuum packed before shipping. 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. VD2 (Pin 1). Supply voltage for output (final) stage collector bias (typically 3.5 V). Bypassing of VD3 is accomplished with C2 and C3 and should be placed in the approximate location shown on the Evaluation Board, but placement is not critical. Please refer to Skyworks’ solder reflow application note, available at www.skyworksinc.com, for instructions on mounting the SKY65146 to a printed circuit board. Ground (Pins 2, 3, 6, 11, 13, 16, 19, 20, 23–28). 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. Production quantities of this product are shipped in a standard tape and reel format. For packaging details, refer to the Skyworks Application Note, Tape and Reel, document number 101568. No Connect (Pins 4, 5, 9, 10, 14, 17, 18, 21). The pins are open and may or may not be connected to ground. Electrostatic Discharge (ESD) Sensitivity The SKY65146 is a static-sensitive electronic device. Do not operate or store near strong electrostatic fields. Take proper ESD precautions. VD4 (Pin 7). Supply voltage for base bias circuitry to all stages (typically 3.5 V). Bypassing of VD3 is accomplished with C1 which should be placed in the approximate location shown on the Evaluation Board, but placement is not critical. Theory of Operation VREG (Pin 8). VREG is the regulated bias enable control voltage to the silicon CMOS controller, 0.0 V = Off, 2.75 V = On. Nominal “On” operating range is between 2.65 VDC and 2.85 VDC. VREG set to 0 VDC will force the amplifier into standby mode. The SKY65146 is a fully matched 3-stage GaAs HBT power amplifier module consisting of on-chip interstage matching circuits and bias circuitry. The input and output match is realized off-chip, but within the module package. The amplifier employs series feedback on the first and second stages to provide for high gain and stability and power of up to 4 W. RF_IN (Pin 12). Amplifier RF Input Pin. ZO = 50 Ω. The module includes an onboard internal DC blocking capacitor. All impedance matching is provided internal to the module. The module includes a silicon CMOS controller circuit to provide a regulated bias enable control, VREG (0–2.75 V) for amplifier On/Off operation. In off operation, supply current is a few microamperes with VREG = 0 V. The module operates with all positive DC voltages while maintaining high efficiency and good linearity. The nominal operating voltage is 3.5 V for maximum power, but can be operated at slightly lower voltages for other mobile applications. VD3 (Pin 15). Supply voltage for driver collector bias (typically 3.5V). Bypassing of VD3 is accomplished with C4 and C5 which should be placed in the approximate location shown on the Evaluation Board, but placement is not critical. RF_OUT (Pin 22). Amplifier RF Output Pin. ZO = 50 Ω. The module includes an onboard internal DC blocking capacitor. All impedance matching is provided internally to the module.

Voltage on VREG pin may not exceed the applied VCC voltage. Performance is guaranteed only under the conditions listed in the specifications table and is not guaranteed under the full range(s) described by the Absolute Maximum specifications. Exceeding any of the absolute maximum/minimum specifications may result in permanent damage to the device and will void the warranty. Each absolute maximum rating listed is an individual parameter. Biasing and driving the amplifier with more than one absolute maximum rating listed may result in permanent damage to the device. Exposure to maximum rating conditions for extended periods may reduce device reliability. CAUTION: Although this device is designed to be as robust as possible, ESD (Electrostatic Discharge) can damage this device. This device must be protected at all times from ESD. Static charges may easily produce potentials of several kilovolts on the human body or equipment, which can discharge without detection. Industry-standard ESD precautions must be employed at all times. Center attachment pad must have a low inductance and low thermal resistance connection to the customer's printed circuit board ground plane.

A DATA SHEET • SKY65146 Evaluation Board GND Evaluation Board Description VCTL VREG VD4 VD3 VD2 VD1 The Skyworks SKY65146 Evaluation Board is used to test the performance of the SKY65146 power amplifier module. The following design considerations are general in nature and must be followed regardless of final use or configuration. GND 1. Paths to ground should be made as short as possible. + C1 2. The ground pad of the SKY65146 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. C2 + C3 INPUT SKY65146 NOTE: Junction temperature (TJ) of the device increases with a poor connection to the slug and ground. This reduces the lifetime of the device. C5 C6 + + C4 C7 IDEN TEST FIXTURE Application Board Test Procedure Capacitors C6 and C7 are shown on EVB, but are not used. Step 1. Connect RF test equipment to Amplifier input/output SMA connectors. Recommended Solder Reflow Profiles Step 2. Connect DC ground. Refer to the “Recommended Solder Reflow Profile” Application Note. Step 3. Connect all VCC (VD) lines to 3.5 V supply and VREG to 2.75 V. Verify the ICQ current is approximately 329 mA. Step 4. Apply RF signal data -30 dBm level and observe that the output level is approximately 8 dBm or the gain of the device is approximately 38 dB. Tape and Reel Information Refer to the “Discrete Devices and IC Switch/Attenuators Tape and Reel Package Orientation” Application Note. NOTE: It is important that the VD2, VD3, and VD4 voltage source be adjusted such that 3.5 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.
