PRELIMINARY DATA SHEET • SKY65337-NP TRANSMIT/RECEIVE FRONT-END MODULE
Technical Description
Transmit/Receive (T/R) Enable
Pin 27 (TX_EN) and pin 12 (RX_EN) are used to enable the
transmit and receive port, respectively.
T/R Switch
Pin 28 (T_R) is used to control the T/R switch.
T/R Enable and T/R Switch Mode Control
The following control logic is used to configure the transmit or
receive mode of the SKY65337-NP:
High Power and Low Power Modes
High power mode output is 20 dBm and low power mode output
is 10 dBm. Pin 26 (TX_HLB) sets the transmit path in high power
or low power mode according to the following logic:

Bottom Center Paddle
The bottom center paddles must be electrically grounded for
proper RF performance. Customers should place adequate
thermal vias under the ground paddles for optimum thermal
performance. The Evaluation Board layout (see Figures 3 and 4)
can be used as a guide for RF ground and thermal layout.
Tx/ Rx Mode Control with limited Fast Control Lines
If only one fast analog control line is available for module
configuration, users can connect the RX_EN pin to 3 V, and
connect the TX_EN and T_R control lines together as follows:
