The RL3500 from Reserved Radeus Labs is a Satellite Beacon Receiver with an L-band input frequency range of 930-2300 MHz. This beacon receiver has a frequency selection of 1 kHz steps and an input level of -100 to -40 dBm. It has a level adjustment of 0.5 dB steps (digital) and a minimum input level of -115 dBm for lock. The receiver has a tracking slope of 0.25-1.0 V/dB and a tracking linearity of +/- 0.25 dB. It supports Ethernet connectable GUI and RS-232, RS-422, and RS-485 interfaces for remote monitoring and control. The receiver uses a non-coherent, FFT detection method and is 5G ready with multiple acquisition bandwidths to reduce the impact of ranging and modulation. It requires an AC supply voltage of 90-260 V and has a power consumption of 45 W. It measures 19 x 16 x 1.75 inches and is ideal for step track and uplink power control applications.
