Product overview
The Xingkai 6.1-7.2G is a 64-channel video receiver for FPV drone video links. Its architecture combines FM/PLL demodulation, PLL local oscillator control and an OLED display showing band, channel and received signal strength. The receiving range is 6100–7200MHz, with a 480MHz intermediate frequency. For integration into a video receiving setup, the electrical interfaces specify a typical 50Ω antenna input and CVBS video output with typical 75Ω impedance, typical 1Vp-p level and negative polarity.
Electrical integration requires a 5–28V supply, with maximum current consumption specified as 600mA. Operating temperature spans -10 to +65℃, storage temperature spans -30 to +85℃, and operating humidity is specified as 85% RH. Video signal-to-noise ratio is at least 38dB. Sensitivity has two distinct stated values: -98dBm in the feature description and a -85dBm minimum in the technical parameters under indoor interference-free test conditions. These differing sensitivity figures are a material distinction when assessing the receiver for a particular link.
