APEX1519 COFDM Close-Packed Transmitter

The APEX1519 is a COFDM close-packed transmitter in a micro-size aluminum alloy casing with good impact resistance, measuring 120*66*30mm and weighing 354g with battery, built to be carried anywhere a video link is needed.

Using COFDM all-digital modulation and demodulation technology, it has strong anti-interference ability and stably transmits image signals in complex electromagnetic environments, with high, clear and stable image quality and no tailing phenomenon. Efficient H.264 image compression ensures stable digital transmission and high-quality audio and video signals.

With a working frequency of 300MHz~2.7GHz customized, 1W output power, 2~8MHz adjustable working bandwidth, QPSK, 16QAM and 64QAM constellations, AES encryption and non-line-of-sight transmission over 1~2km, the APEX1519 accepts HDMI video and audio as well as analog CVBS input for flexible field video transmission.
