DESCRIPTION
Figure 6: SC Series Block Diagram
The TR-XXX-SC module is a single-channel, half-duplex transceiver designed for
the wireless transmission of digital or analog information over distances of <500
feet outside and <200 feet inside.
No external components (excluding an antenna) are required. The module
incorporates an on-board switch allowing the use of a single antenna. Linx offers
a wide selection of antennas designed for use with the transceiver module.
The transceiver is half-duplex; therefore, it can only be operated in one mode at
a time: either transmit mode or receive mode. When transmitting, the receiver is
powered down. Likewise, the transmitter is powered down in receive mode.
The transmit section of the transceiver is capable of producing up to 1mW of
output power while maintaining harmonics and spurious emissions within legal
limits. The power amplifier can be adjusted over a 15dB adjustment range via
the LVLADJ pin. This is very useful for optimizing a product during FCC testing.
The transmitter directly modulates the carrier with the baseband signal present
at the TXDATA pin. If the signal is analog in nature, it will FM modulate the carrier.
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
-94dBm (typical). The receiver operates in a single conversion superhet
configuration, with an IF of 10.7 MHz. A quadrature demodulator is used to
recover the baseband analog signal from the carrier. This analog signal is low-
pass filtered and then made externally available to the user via the audio pin. It
is also passed to the data slicer for squaring of digital content.
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).
