Description
The Skyworks SKY65313-21 is a high-performance,
transmit/receive (T/R) front-end module (FEM). The device
provides a complete T/R chain with T/R switches.
The device transmit chain features +30.5 dBm output power and
a 40 percent power-added efficiency (PAE).
The device receive chain features a Low Noise Amplifier (LNA)
with a 1.4 dB noise figure (NF) and 16.6 dB gain. The cascaded
NF and gain, taking into account the 0.5 dB insertion loss
transmit/receive antenna switch, are 1.9 dB and 16.1 dB,
respectively, which makes the SKY65313-21 ideal for medium
power microwave links such as 900 MHz Industrial, Scientific and
Medical (ISM) band applications.
The module also has a shut-down 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-Mounted Technology (SMT) package, which
allows for a highly manufacturable low-cost solution.
The device package and pinout are shown in Figure 1. A block
diagram of the SKY65313-21 is shown in Figure 2. Signal pin
assignments and functional pin descriptions are provided in

Technical Description
The SKY65313-21 consists of a complete T/R chain with T/R
switches contained in the module. A single-pole, double-throw
(SPDT) switch selects between the receive and transmit paths.
The module has a shut-down mode to minimize power
consumption.
Three digital input pins (CTL1, CTL2, and CTL3) are used to select
between transmit, 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 SPDT 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.
Receive Path
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 SPDT switch and the LNA input are connected to module
pins to allow an external filter to be inserted into the receive path.
Operation Mode Control
The four SKY65313-21 operating modes are controlled by the
three digital pins: CTL1, CTL2, and CTL3 (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 SKY65313-21 are provided
in Table 3. Recommended operating conditions are specified in
Table 4. Electrical specifications are provided in Tables 5, 6,
and 7.
Typical performance characteristics of the SKY65313-21 are
illustrated in Figures 3 through 22.

In the high state, CTL1, CTL2, and CTL3 have an input current of 33 μA due to an internal 100 kΩ pulldown. In the shutdown mode, for the lowest leakage current, the high state is not
recommended for CTL1 and CTL3.

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
The SKY65313-21 Evaluation Board is used to test the
performance of the SKY65313-21 T/R FEM. A typical application
schematic diagram is provided in Figure 23. An Evaluation Board
schematic diagram is provided in Figure 24. An assembly drawing
for the Evaluation Board is shown in Figure 25.
Package Dimensions
A typical part marking is shown in Figure 26. The PCB layout
footprint for the SKY65313-21 is provided in Figure 27. Package
dimensions are shown in Figure 28, and tape and reel dimensions
are provided in Figure 29.
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
subjected to high temperature during solder assembly.
The SKY65313-21 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.
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.
