range extender. The device provides a complete T/R chain with
T/R switches.
• Internal RF match and bias circuits
• All RF ports internally DC blocked
• Shutdown mode
• Small footprint, MCM (28-pin, 6 x 6 mm) package
(MSL3, 260 °C per JEDEC J-STD-020)
Skyworks GreenTM products are compliant with
all applicable legislation and are halogen-free.
For additional information, refer to Skyworks
Definition of GreenTM, document number
SQ04–0074.
The device transmit chain features +30.2 dBm output. The device
receive chain features a low-noise amplifier (LNA) with a 1.8 dB
noise figure (NF) and 21 dB gain. The cascaded NF and gain,
taking into account the 0.4 dB insertion loss transmit/receive
antenna switch, are 2.2 dB and 20.6 dB, respectively.
The module also has a shutdown mode, PA bypass mode, and
LNA bypass mode to minimize power consumption.
The device is mounted in a 28-pin, 6 x 6 mm Multi-Chip Module
(MCM) surface-mount technology (SMT) package, which allows
for a highly manufacturable low-cost solution.
A block diagram of the SKY65366-21 is shown in Figure 1. The
device package and pinout for the 28-pin MCM are shown in
Figure 2. Signal pin assignments and functional pin descriptions
are provided in Table 1.

DATA SHEET • SKY65366-21: 400 MHz TRANSMIT/RECEIVE FRONT-END MODULE
Technical Description
Receive Path
The SKY65366-21 consists of a complete T/R chain with T/R
switches contained in the module. A single-pole,
triple-throw (SP3T) switch selects between the receive, transmit,
and transmit bypass paths. The module has a shutdown mode to
minimize power consumption.
The receive path contains an LNA with bypass switch. The LNA
impedance matching networks are internal to the module and
have been optimized for a low NF while maintaining good return
losses into a 50 Ω source and load impedance. The receive arm
of the SP3T switch and the LNA input are connected to module
pins to allow an external filter to be inserted into the receive path.
Three digital input pins (TR, EN, and BYP) are used to select
between transmit, transmit bypass, receive, receive bypass, or
shutdown mode.
Transmit Path
The transmit path contains a power amplifier (PA) optimized for
saturated performance. The PA output is internally matched for
optimum output power and efficiency into a 50 Ω load
impedance. The PA output is passed through an harmonic filter
before being fed through the SP3T switch. The PA input provides
a good return loss into a 50 Ω source impedance.
Transmit output power is controlled by the VPC pin, which is
normally set to 2.25 V DC voltage. The nominal DC input
impedance into the VPC pin is 50 kΩ.
Operation Mode Control
The five SKY65366-21 operating modes are controlled by the
three digital pins: TR, EN, and BYP (pins 2, 3, and 4, respectively).
The control logic truth table is provided in Table 2.
Electrical and Mechanical Specifications
The absolute maximum ratings of the SKY65366-21 are provided
in Table 3. Recommended operating conditions are specified in
Table 4. Electrical specifications are provided in Tables 5, 6,
and 7.

1 See Table 4 for logic 0 and 1 characteristics. “X” = don’t care state, defined as a valid state of logic 1 or 0. Control signals must be a valid logic 1 or 0.
Performance is not guaranteed if control inputs are floated.
2 In the high state, TR, EN, and BYP have an input current of 33 μA due to an internal 100 kΩ pulldown resistance. For the lowest leakage current, the high state is not recommended for TR
and BYP when the device is in shutdown mode (EN = 0).

1 Exposure to maximum rating conditions for extended periods may reduce device reliability. There is no damage to device with only one parameter set at the limit and all other parameters set
at or below their typical value as provided in Table 4.
2 Nominal thermal resistance, junction-to-case, is 18 °C/W.
CAUTION: Although this device is designed to be as robust as possible, electrostatic discharge (ESD) 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 should be used at all times.

Evaluation Board Description
Package and Handling Information
The SKY65366-21 Evaluation Board is used to test the
performance of the SKY65366-21 Transmit/Receive Range
Extender. A typical application schematic diagram is provided in
Figure 3. A Low-Pass Filter (LPF) can be incorporated on the ANT
port to provide additional rejection of PA output harmonic levels
and/or limit unwanted signals from entering the receive path. A
three-section LPF is indicated for this function in Figure 3.
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.
The SKY65366-21 is rated to Moisture Sensitivity Level 3 (MSL3)
at 260 °C. It can be used for lead or lead-free soldering. For
additional information, refer to Skyworks Application Note, PCB
Design and SMT Assembly/Rework Guidelines for MCM-L
Packages, document number 101752.
An Evaluation Board schematic diagram is provided in Figure 4.
Typical part marking appears in Figure 5. An assembly drawing
for the Evaluation Board is shown in Figure 6, and the layer detail
is provided in Figure 7.
Care must be taken when attaching this product, whether it is
done manually or in a production solder reflow environment.
Production quantities of this product are shipped in a standard
tape and reel format.
Package Dimensions
The PCB layout footprint for the SKY65366-21 is provided in
Figure 8. Package dimensions are shown in Figure 9, and tape
and reel dimensions are provided in Figure 10.

Notes:
Some component labels may be different from the corresponding component symbol shown here.
Component values, however, are accurate as of the date of this data sheet.
PCB Recommendations:
Metal Layer 1 = RF traces + control lines. Core thickness between top RF layer and ground plane is critical.
Metal Layer 2 = Solid ground plane. No traces routing.
Metal Layer 3 and 4 = Control lines + VCC traces (no VCC plane).
Pour copper on each layer connected to the ground plane. Use VCC traces in a star distribution pattern.
Always use 4 layers.
