RTL2832U With antenna

Versatile RTL2832U SDR Receiver Module with Integrated Antenna

The RTL2832U is a low‑cost, high‑performance Software‑Defined Radio (SDR) chip that offers a continuous frequency coverage from 500 kHz to 3.8 GHz, making it ideal for wideband signal acquisition and real‑time demodulation. This module, paired with a high‑gain UHF antenna, provides an out‑of‑the‑box solution for hobbyists, researchers, and engineers applying SDR in radio spectroscopy, digital television reception, GNSS decoding, and amateur radio monitoring.

Its micro‑controller interface (I2C) allows for flexible configuration of tuner settings, while the 8‑bit ADC delivers 1 MHz sample rates up to 4 Msps, giving fine-grained access to RF spectra. The compact design with an SMA/UF‑LP connector and onboard bias‑tee keeps cost and size low without sacrificing performance.

• Frequency Range: 500 kHz–3.8 GHz
• ADC Sampling: 1 Msps (up to 4 Msps at 1 MHz IF)
• Interface: I2C, micro‑USB for power and control
• Common Use Case: Rapid‑prototyping SDR, spectral scanning, FM/TV broadcasting, GPS signal reception, and digital signal processing projects
