Overview
TRX-310 is TSI’s latest offering for 2-way wireless
broadband Internet application at UHF band. It
accepts an IF signal of 30~42MHz from cable
modem, upconverts the signal to 704~716MHz and
transmits it back to the MMDS headend site.
With its built-in automatic on/off switch, TRX-310
will enter sleep mode to eliminate the broadband
noise when there is no data packet transmission.
Without exception, TRX-310 embodies the long
term stability and reliability common to all TSI
products.
With the integrated downconverter and
upconverter, TRX-310 provides the best cost /
performance solution for your 2-way MMDS
operation.
