MODULE
Description
The SKY65146 is a fully matched 28-pin surface mount multi-chip
module (MCM) amplifier designed for Private Mobile Radio,
Wireless Local Loop, and TDMA/AMPS mobile units operating in
the 806-849 MHz cellular bandwidth. 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 the interstage
matching circuit. 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 Ωload.
Primary bias to the SKY65146 can be supplied directly from a
single cell lithiumion 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.
Skyworks offers lead (Pb)-free, RoHS (Restriction of
Hazardous Substances)-compliant packaging.
NEW
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.

1. For pulsed operation with duty cycle < 25%.
2. When amplifier is biased off (VREG = 0 V).
3. 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 poten-
tials of several kilovolts on the human body or
equipment, which can discharge without detection.
Industry-standard ESD precautions must be employed
at all times.

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 the
device if solder migration is an issue.
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.
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.
No Connect (Pins 4, 5, 9, 10, 14, 17, 18, 21). The pins are open
and may or may not be connected to ground.
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.
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.
RF_IN (Pin 12). Amplifier RF Input Pin. ZO= 50 Ω. The module
includes an onboard internal DC blocking capacitor. All imped-
ance matching is provided internal to the module.
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.
Package and Handling Information
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 sub-
jected to high temperature during solder assembly.
Please refer to Skyworks’ solder reflow application note, available
at www.skyworksinc.com, for instructions on mounting the
SKY65146 to a printed circuit board.
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.
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.
Theory of Operation
The SKY65146 is a fully matched 3-stage GaAs HBT power
amplifier module consisting of on-chip interstage matching cir-
cuits 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.
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.

Evaluation Board Description
The Skyworks SKY65146 Evaluation Board is used to test the
performance of the SKY65146 power amplifier module. The fol-
lowing 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 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.
NOTE: Junction temperature (TJ) of the device increases with a
poor connection to the slug and ground. This reduces the
lifetime of the device.
Evaluation Board Test Procedure
Step 1. Connect RF test equipment to Amplifier input/output SMA
connectors.
Step 2. Connect DC ground.
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.
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 sig-
nificantly if long leads are used. Adjust the bias voltage to
compensate.
