Image of Electronic Communication Systems FZC - High-throughput X-band Transmitter on the satsearch marketplace

Key highlights

The High-throughput X-band Transmitter is flexible, implementing various payload data interfaces, control/telemetry interfaces, payload data framing protocols (CCSDS or GSE) and allowing in-flight adaptive coding and modulation per DVB-S2 standard.

Features

Operates in the 8050-8400 MHz X-band allocation for Earth science satellites
Features high throughput in the cubesat formfactor
Implements flexible state-of-the-art modulation and error correction coding
Provides adaptive coding and modulation to maximize throughput for various Es/No
Customizable data and control interfaces

Key features

DVB-S2 framing, coding and modulation ensures compatibility with many off-the-shelf demodulators and ground station networks
Symbol rate 250 Msymb/s (optional 280 Msymb/s)
Modulation QPSK, 8PSK, 16APSK (optional 32APSK)
Transmit data rate 0.5 - 1.12 Gbps
Payload (useful) data rate 250 - 1000 Mbps

Customization

The transmitter features two possible payload data interface options

Ethernet 1000Base-T
LVDS

and various control and telemetry interface options

RS-422
CMOS level UART
CAN-2B.

The LVDS interface is a 4-bit wide DDR parallel interface with frame-level flow control. It is asynchronous w.r.t. transmit baud clock. It is possible to modify this interface according to the customer's needs.

Flight heritage

The High-throughput X-band transmitter has achieved a robust flight heritage. It is used in at least six LEO missions, the first was launched in January 2023. All are still operational as of October 2025.
