DRF-TR001( LW2110, LW2110PK2B) Wireless Digital Transceiver ELANsat PCB layout guideline Any metal (including PCB track and holding screw) around the antenna will result in changing impedance and radiation pattern of the antenna. These two parameters are the most important for antenna performance. Reserve space around the antenna as much as possible.
DRF-TR001( LW2110, LW2110PK2B) Wireless Digital Transceiver ELANsat Operation Block Diagram of DRF-TR001 The SPI data then is fed to SOIC for encoding, FSK-modulation, frequency conversion, and amplification. RF signal between SOIC and antenna is separated to two paths: transmission and receiving (by two RF switches). Transmitted RF Signal from SOIC is following by a power amplifier to increase output power and transmission distance.
(LW2110, LW2110PK2B) UCZM2110 15.247 8：2010 8575A-LW2110 8 UCZM2110 8575A-LW2110 Under Industry Canada regulations, this radio transmitter may only operate using an antenna of a type and maximum (or lesser) gain approved for the transmitter by Industry Canada. To reduce potential radio interference to other users, the antenna type and its gain should be so chosen that the equivalent isotropically radiated power (e.i.r.p.) is not more than that necessary for successful communication.
