SDR-RF 2400AD module is an advanced low power and high performance RF transmitter-receiver implemented with Fractional-N Phase-Locked Loop (PLL) to achieve linearity of frequency modulation, enhance performance of target detection, and improve range resolution.

It operates at 24-26 GHz frequency and is intended to interface with the processor module SDR-PM 402, which functions as a micro controller, processor and power management with a 24-pin flat flex cable (FFC) to form a standalone system.

Typical output power of the transmitter channel is 16dBm. Single-ended SMA female connectors are installed for easy connection to antennas.

Its receiver has an overall 6.4dB noise figure with one stage of low-noise amplifier and exceptionally linear response with a flat gain of 28dB.

The ability of wide-range frequency-tuning makes this RF module ideal for applications from unlicensed ISM band to high-resolution wide-band.
