Description
The SKY85203-11 integrates a single-pole, triple-throw (SP3T)
switch and low-noise amplifier (LNA) with a bypass mode in an
ultra-compact package. The device is capable of switching
between WLAN receive, WLAN transmit, and Bluetooth.
The SKY85203-11 is provided in a small Quad Flat No-Lead (QFN)
12-pin, 2 x 2 mm package. A functional block diagram is shown
in Figure 1. The pin configuration and package are shown in
Figure 2. Signal pin assignments and functional pin descriptions
are provided in Table 1.

Evaluation Board Description
The SKY85203-11 Evaluation Board is used to test the
performance of the SKY85203-11 LNA FEM. An Evaluation Board
schematic diagram is provided in Figure 3. A photograph of the
Evaluation Board is shown in Figure 4.
Evaluation Board Setup Procedure
1. Connect the system ground to pin 19 of connector J9.
2. Apply 3.3 V to VDD pin 17 of connector J9.
3. Refer to the Control Logic Table in Table 8 to set the device in
the desired mode of operation. Set CRX, CTX, CBT, and LEN to
appropriate VIL and VIH voltages, as specified in Table 3.
4. Transmit performance is monitored by applying an RF signal to
the connector J4 (TX) and measuring the output power at the
antenna port connector J3 (ANT).
5. Monitor the receive performance in either high gain or bypass
mode by applying an RF signal to the antenna port connector
J3 (ANT) and measuring the output power at the receive port
connector J2 (RX).
6. Monitor the Bluetooth performance by applying an RF signal to
the antenna port connector J1 (BT) and measuring the output
power at the receive port connector J3 (ANT).
Evaluation Board Losses
The total track losses from the RF connectors of the Evaluation
Board to the flip chip die bumps of the SKY85203-11 are:
ANT: 0.22 dB
TX: 0.22 dB
RX: 0.22 dB
BT: 0.36 dB
Package Dimensions
The PCB layout footprint for the SKY85203-11 is provided in
Figure 5. Typical part markings are shown in Figure 6. Package
dimensions for the 12-pin QFN are shown in Figure 7, and tape
and reel dimensions are provided in Figure 8.
Package and Handling Information
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 SKY85203-11 is rated to Moisture Sensitivity Level 1 (MSL1)
at 260 C. It can be used for lead or lead-free soldering. For
additional information, refer to the Skyworks Application Note,
Solder Reflow Information, document number 200164.
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.
