## Editorial
HDRTx-1.5 is Dragonfly Aerospace's dual-channel X-band transmitter for micro and mini satellites in LEO.[^dragonfly-hdrtx15-page]

Dragonfly presents the HDRTx-1.5 technology as flight-proven, ITAR-free, and TRL 9.[^dragonfly-hdrtx15-page][^dragonfly-components-overview]

The transmitter uses DVB-S2 encoding with dynamic modulation to optimize link margin and data throughput, and its maximum data rate is 1.5 Gbps.[^dragonfly-hdrtx15-page]

Its electrical and thermal envelope includes a 20-40 V supply range, configuration-dependent power consumption below 33 W, and -10 C to +50 C operation.[^dragonfly-hdrtx15-page]

The unit measures 175 x 145 x 55 mm, has mass below 1.6 kg, and has a design life of up to 8 years in LEO.[^dragonfly-hdrtx15-page]

Its RF section covers 8.025-8.4 GHz and provides 4 W in single-channel mode or 2 W per channel in dual-channel mode.[^dragonfly-hdrtx15-page]

Maximum symbol rate is 150 + 150 Msps in dual-channel mode or 300 Msps in single-channel mode.[^dragonfly-hdrtx15-page]

Telemetry and telecommand interfaces are CAN, I2C, and RS485, while high-speed data interfaces are GTx and LVDS.[^dragonfly-hdrtx15-page]
