SC-PA SERIES TRANSCEIVER MODULE DESIGN GUIDE
The PA version of Linx popular SC Series greatly reduces the time and
expense of making a product wireless. This is because the transceiver
module is pre-approved by the FCC when used with the appropriate
proprietary antennas.The TR-XXX-SC-PA transceiver module is
designed for the cost-effective, bi-directional transfer of wireless
information. The Transceiver utilizes an advanced synthesized
superhet architecture and has direct interface for analog or digital
information, UART-compatible data output, RSSI, low power
consumption, wide operational voltage, on-board TX/RX switch, SAW
front-end filter, and many other useful features. Fast turnaround times,
along with the support for data rates to 33.6Kbps, make the
transceiver suitable for a wide range of applications. Housed in a
compact through-hole package, the transceiver requires no tuning or
external RF components (except antenna), allowing for straightforward
application, even by engineers lacking previous RF experience.

... The transceiver has an on-board voltage regulator that regulates the internal VCC to 3.0V. This allows a wide operating voltage range of 2.7V to 13V. At 2.7V, the internal regulator acts as a saturated switch, directly passing voltage through to the internal electronics. The PDN pin can be used to put the transceiver into a low-current sleep mode (<50uA). 10.7MHz 10 ...

... The transmitter is designed to give an average deviation of 110kHz with a 5V square wave input possible to successfully modulate the transceiver with a level as low as 3 volts; however, the reduced carrier deviation will cause a slight loss in receiver sensitivity and 20% increase in settling times. ...

... Interference can manifest itself in many ways. Low-level interference will produce noise and hashing on the output and reduce the link’s overall range. Thanks to the capture properties system, the transceiver will still function when an intended signal is present at a higher level than the interference. ...

... Switch to transmit mode The transceiver is placed in transmit mode by bringing TXEN high and RXEN low. The PDN pin must be open or pulled to VCC. Once the transceiver is placed in transmit mode, the synthesizer will begin trying to lock. 2) Wait for transmitter to stabilize This step is necessary to allow the transmitter time to lock and stabilize ...

... The procedure here is protocol-dependent but to illustrate, let’s consider the packet format outlined above being sent to a UART. A UART interprets the start- bit of a byte as a 1-0 transition. When the incoming data is 101010 or hash... it is hard to actually find the start bit. This problem is solved by the UART Sync Byte. ...

... Fortunately, because of the care taken by Linx in the layout of the module’s PCB, integrating a TR-XXX-SC-PA transceiver into your design is very straightforward. By adhering carefully to a few basic design and layout rules, you can enjoy a trouble-free path to RF success. Figure 8 shows the suggested PCB footprint for the TR-XXX-SC-PA. ...
