Product overview
The Kimpok KP-HDT20W provides wireless video and audio transmission for drone applications through a transmitter and receiver architecture. The transmitter combines COFDM modulation with an adjustable 10-20W RF output and two cooling fans. Its 220*140*66mm enclosure weighs 2.5kg, establishing the space and mass required for installation. It operates from DC12V with current of ≤6A@DC12V. Video connections comprise HDM-I/SDI and CVBS; RS232/TTL data input is optional and supports up to 115200bps. The hardware is a communications subsystem rather than a flight platform or airframe kit.
The receiver uses a 1U chassis weighing 1.5kg and provides an N-type, 50Ω RF input, alongside SDI/HDM-I/ASI and two audio plus two video outputs. Its video specification includes 1080P at 4MHz bandwidth. Both units cover 300-900MHz, with other frequencies available by customization, but their bandwidth selections differ. Integration must also accommodate separate temperature limits: -25°C~55°C for the transmitter and -20°C~+50°C for the receiver. Transmitter coding includes MPEG-2/H.264/H265, while receiver coding is specified as MPEG-2/H.265; optional transmitter settings and data connectivity remain configuration choices.
