2023年5月18日 · The Block Upconverter (BUC) is a device that’s used in the transmission (uplink) of satellite signals. Its fundamental function is to convert low-frequency input signals into high-frequency output signals that can be transmitted to a satellite.

A CPI amplifier with an integrated L-band block upconverter (BUC) offers the opportunity for significant cost and reliability savings in low and medium data rate applications by eliminating costly duplicated functions in the conventional RF terminal chain.

A block upconverter (BUC) is a component used in the transmission (uplink) of satellite signals. It converts a band of frequencies [1] from a lower frequency to a higher frequency. Modern BUCs convert from the L band to K u band, C band and K a band. Older BUCs convert from a 70 MHz intermediate frequency (IF) to K u band or C band.

The widest variety of the most popular satellite VSAT Block Upconverters (BUCs) in C-Band, KU-Band, X-Band and Ka-Band frequencies from NJRC, Codan, Comtech EF Data, Norsat, Terrasat, Paradise Datacom, Wavestream, Belcom Microwaves and more.

On-The-Move (OTM) networking capability. The WIN-T Increment 2 network retains capabilities delivered by WIN-T Increment 1 and by leveraging proven government and commercial technologies, adds greater network throughput and automated Network Management to optimize planning (to include spectrum use), initial.

If the STT is a JNN trailer with both TDMA and FDMA links, the peak and polling Is only required using only one link (TDMA or FDMA). The FDMA link must still be power balanced on the satellite. Drop the unmodulated carrier and begin transmitting the modulated carrier.

Block upconverter, also known as (BUC) is used in uplink of satellite signals. It converts a given band of low frequencies to a higher frequency typically needed for uplink work. Latest block upconverters converts frequencies from L band to S band, C band, x band.
