Description
The SKY65111-348LF is a high-performance 3-stage, highpower amplifier IC designed for use in 600–1100 MHz ISM band
applications such as automatic meter readers and RFID. It has an
integrated analog power control voltage for achieving the desired
output power levels. The IC is manufactured on an advanced
InGaP HBT process. The SKY65111-348LF is packaged in a thermally enhanced, ultrasmall, micro lead frame package.
NEW
Skyworks offers lead (Pb)-free, RoHS (Restriction of
Hazardous Substances)-compliant packaging.

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. Basing and driving the
amplifier with all absolute maximum ratings listed simultaneously may result in permanent
damage to the device.
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.

Incorrect soldering of the device paddle to grounding pad may lead to parasitic oscillations, reduced performance and increased device temperature rise. Uniform coverage over the entire bottom
ground paddle must be maintained to avoid these conditions.

Application Circuit Notes
Ground, (Pins 1, 3, 8, 14). 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. It is extremely important that the device paddle be sufficiently grounded for both thermal and stability reasons. Please
refer to the enclosed Package Footprint.
RF input (Pin 2). A lumped element matching structure for good
in-band return loss has been realized on the RF input, Pin 2. This
structure is comprised of a DC blocking capacitor (C1), low pass
LC filter (L1, C1) and at the device input, a series capacitor (C25).
This combination of devices will yield a return loss better than 11 dB over the entire 800–1100 MHz band of interest. The
placement of C1 is not critical; it can be moved as close to L1,
C2 and C25 as desired. C25 should be placed as close to the
device pin as possible to replicate performance as measured on
the applications board.
VCC1 (Pin 4). VCC1 is the collector bias for the first amplifier
stage in the SKY65111. Multiple bypass capacitors, C3-C5, C17
and a series inductor, L2, have been utilized to ensure stability
both in and out of the useable bandwidth of the device. The
length of transmission line between L2 and Pin 4 is not critical;
L2 can be placed as close to the pin as possible if desired.
However, placement of L2 farther away from Pin 4 than shown
on the Applications Circuit is not recommended. C3 should also
be placed in the approximate location shown on the Applications
Circuit, but placement is not critical.
VREF (Pin 7). VREF is the bias reference voltage for amplifier
stages 2 and 3. VREF should be operated over the same voltage
range as VCC, with a nominal voltage of 3.5 VDC. Bypassing of
VREF is accomplished with C22 and C23 which should be placed
as close to the device pin as possible.
RFOUT, VCC3 (Pins 9-12). RFOUT and VCC3 are the biasing input of
the stage 3 collectors. Bias is applied to the RF output through a
length of transmission line that is approximately 827 mils (21
mm) long. Capacitors C11-C14 provide proper RF bypassing and
should be placed as shown in the Applications Circuit. Output
matching for optimal power gain is accomplished with capacitors
C15 and C16. Spacing between these capacitors with respect to
the RF output and each other is critical and is shown on the
Component Placement Diagram. Special care must be taken
when placing these devices; their locations should not deviate
significantly from the locations as shown. If these capacitors are
not located properly, large decreases in output power and efficiency will occur.
Pin 13. Pin 13 has no connection and should be left open circuit.
VCC2 (Pins 15-16). VCC2 is the collector bias input for the second
amplifier stage in the SKY65111. Multiple bypass capacitors,
C8-C10 have been utilized to ensure stability both in and out of
the useable bandwidth of the device. Capacitor C7 is not populated with the normal tuning configuration described above.
VAPC1 (Pin 5). VAPC1 is the bias control voltage input for amplifier
stages 1 and 2. Nominal operating range is between 2.6 VDC and
2.8 VDC, with 3 VDC producing the minimum attenuation point.
VAPC1 may also be set to 0 VDC, to force stages 1 and 2 into
standby mode.
VAPC2 (Pin 6). VAPC2 is the bias control voltage for amplifier
stage 3. Nominal operating range is between 2.6 VDC and
2.8 VDC, with 3 VDC producing the minimum attenuation point.
A 100 pF capacitor (C19) may be used for bypassing at high
frequencies. The value of this capacitor may also be made large,
greater than 1000 pF, if longer response time is acceptable.
VAPC2 may also be set to 0 VDC, to place amplifier stage 3 into
standby status.
NOTE: In most applications VAPC1 and VAPC2 pins are directly tied
together and biased from the same control voltage. VAPC1
and VAPC2 may also be split if independent control is
desired.

Application Board Bias Procedure

Step 1. Connect DC ground.
Step 2. Connect all VCC and VREF lines to 3.5 V supply, labeled 2.
Step 3. With the RF off, apply 2.7 VDC to VAPC1, 2 control pins.
Verify the ICQ current is approximately 250 mA, labeled 3.
Step 4. Apply RF signal data -30 dBm level and observe that the
output level is approximately 10 dBm or the gain of the
device is approximately 40 dB.
NOTE: It is important that the VCC1, VCC2, VCC3, and VREF 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.
