Pulsar-STX Datasheet Product enquiry

S-band Transmitter

The low power consumption PULSAR-STX solution operates at amateur and commercial bands respectively and is user programmable within bands. This solution has low power requirements with < 5 W (for maximum RF power output) and is powered from unregulated battery bus or regulated 5V.

The transmitter implements QPSK modulation with transmission data rates of up to 2 Mbps. It utilises an open network encoding scheme based on the IntelSAT IESS-308 specification which allows this product to be used with low-cost commercial satellite receivers. The transmitter is ideal for space missions where a high data rate downlink is required. The PULSAR-STX solutions have been tried, tested and trusted on an array of on orbit missions proving to be not only reliable but efficient. The PULSAR-STX was part
of the UKube-1 mission, the UK Space Agency’s first national spacecraft. These transmitters are compatible with our S-Band Patch Antenna. These solutions are supplied with user manuals, flight boards and STEP files for seemless system integration.
