... If the signal is digital, the modulation method becomes FSK. In either case the carrier’s peak deviation is determined by the modulating signal’s amplitude. The receive section of the transceiver is capable of recovering a signal as low as -95dBm (typical). The receiver operates in a single conversion superhet configuration, with 10.7 MHz. A quadrature demodulator is used to recover the baseband analog signal from the carrier ...

... The transmitter’s output power is not affected by supply voltage but it can be externally adjusted from approximately -15dBm to 0dBm using the LVLADJ pin. When the LVLADJ pin is open, power is at its max and the transmitter will draw 25mA typically. When LVLADJ is at 0V, power is at its minimum and the transmitter will draw 13mA typically ...

... 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. ...

... This will invalidate the timing parameters and may cause illegal emissions from the transceiver. 3. Required transition interval. This is the maximum amount of time that can elapse without a transition on the TX data pin always important to think of data in both the analog and the digital domain. ...

... 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. ...

... The trace from the transceiver to the antenna should be kept as short as possible. A simple trace is suitable for runs up to 1/8 inch for antennas with wide bandwidth characteristics. For longer runs or to avoid detuning a high-Q narrow bandwidth antenna such as a helical, use a 50-ohm coax or 50-ohm microstrip transmission line as described in the following section ...
Page 12
... This term refers to a PCB trace running over a groundplane which is designed to serve as a transmission line between the module and the antenna. The width is based on the desired characteristic impedance, the thickness of the PCB, and its dielectric constant ...

... To fully appreciate the importance of an antenna that is both resonant and matched consider that an antenna with a VSWR of 1.5 will effectively transmit approximately 95% of its power while an antenna with a VSWR of 10 will only transmit about 30%. give its ...

... For this reason the antenna shaft and tip should be positioned as far away from such objects as possible. 2. Optimum performance will be obtained from a 1/4- or 1/2-wave straight whip mounted at a right angle to the groundplane. In many cases this isn’t desirable for practical or ergonomic reasons; thus, an alternative antenna style such as a helical, loop, patch, or base-loaded whip may be utilized ...

... To meet this need, Linx offers a wide variety of straight and reduced-height whip-style antennas in permanent and connectorized mounting styles. The wavelength of the operational frequency determines an antenna's overall length ...

... The modules are wash resistant, but are not hermetically sealed. They may be subject to a standard wash cycle; however, a twenty-four-hour drying time should be allowed before applying electrical power to the modules. This will allow any moisture that has migrated into the module to evaporate, thus eliminating the potential for shorting during power-up or testing ...
