Features:
RD620II receiver – a small and light receiver with high‐performance using the latest in receiver technology.
Sensitivity of DUAL Conversion Receiver
RS620II has improved the range as far as 1.8Km*
*This range is based on our test conditions. The actual result of a range check will be different depending on your local environment.
Dual Conversion receiver can eliminate mirror frequency interference efficiently. Further remote control distance means more reliable control. Even the reliability can compare beauty with PCM receiver. We make control distance be further so that receiver can locate in stable RF Electromagnetic Field, it will make the reliability of Corona receiver approach to PCM receiver. Meanwhile, its response speed will not be influenced.
Selectivity and Dual Ceramic IF filter
The RD620II uses dual tuned RF circuitry with dual ceramic IF filters. Compared to a single ceramic filter, it has a better steep flank which reduces group delay effectively and ensures that the receiver has ultra narrow selectivity to more effectively reject adjacent channel interference. This is especially important when flying indoor airplanes where many transmitters may be operating near each other.
IP3&AGC
With improved circuit design, RD620II advances IP3 performance apparently, and it can even compare beauty with all famous brand receivers around the world. Now RD620II can operate under more 3 adjacent channel transmitters.
DSP
Improved DSP algorithm, It can make more strictly filter about received signals and eliminate glitch efficiently.

RD620II receiver has the structure of level inserted pin by special design and assorted with super thin electronic parts. The thickness of RD620II receiver is only 7.2mm which make the installation more convenient.

Reliability, high performance and sale price, they are what CORONA can provide for you.
