Product overview
The DMKR 1.2G 9CH Analog VRX Module is an analog FPV video receiver. It is a component, not a flight platform or airframe. It receives analog video in the 1.2GHz band on 9 selectable channels and demodulates it with an FM/PLL system. Rated sensitivity is -95dBm, aimed at typical FPV goggle use and short-to-mid range UAV applications. Audio is carried on subcarriers at 6.0MHz (AR) and 6.5MHz (AL). The RF input has a typical impedance of 50Ω and a VSWR rating of 2:1. The video output impedance is 75Ω.
A single-layer PCB keeps the module to 44×27×27mm and 20g without the antenna. That size suits direct integration into goggles, portable receivers and lightweight UAV ground systems. The antenna connects through an SMA connector. The module accepts 7–36V DC input and draws (280±40)mA at 5V, and an on-board regulator provides a 5V 1A RX output. IRC Tramp protocol support lets you adjust frequency and power remotely through a flight controller or OSD interface. For higher signal stability or complex RF environments, the manufacturer recommends a separate dual-layer enhanced version instead of this single-layer module.
