R820T2 RTL2832U 1PPM TCXO SMA Software Defined Radio USB Dongle For RTL-SDR Blog

Description: Product Description Features:This RTL SDR unit has several improvements over generic and other brands including:R820T2 tunerImproved passive component tolerancesA 1 PPM temperature compensated oscillator (TCXO)HF mode via direct sampling built in (can tune down to 500 kHz unlike basic RTL-SDRs which can only go to 24 MHz)SMA F connectorAluminium shielded case with thermal pad for passive cooling to improve L-Band performanceSoftware activatable 4.5v bias tee circuitImproved PCB design for lower noise and less spursA USB noise choke, more bypass capacitors, and built in ferrites for less PC noiseImproved ESD protection (additional ESD diode and extra ESD discharge paths)An improved front end circuit designed for wideband use (other models still use a circuit designed for DVB-T only)Several breakout pads on the PCB for advanced usersThis is an RTL-SDR software defined radio receiver with RTL2832U ADC chip, R820T2 tuner, 1PPM TCXO, SMA F connector and aluminium case with passive cooling. Tunes from 500 kHz to 1.7 GHz with up to 3.2 MHz of instantaneous bandwidth (2.4 MHz max stable, 3.2 MHz max if your application is tolerant to USB drops). (HF works in direct sampling mode - V.3 models and above only). Perfect for use as a computer based radio scanner with free software like SDR#, HDSDR, SDR-Radio, Linrad, GQRX or SDR Touch on Android. Works on for Windows, for MacOS, for Linux, Android and even embedded for Linux computers like the Raspberry Pi.This model has several key improvements over other models. It uses the improved R820T2 tuner, has a 1PPM TCXO (2 PPM initial offset, 1 PPM temperature drift), has improved component tolerances and an SMA F connector. It also comes with a software activatable bias-tee circuit for powering external devices such as LNAs and active antennas. It also has HF reception capabilities. Most standard RTL-SDR dongles can tune down to 24 MHz at the lowest. This model has hardware that unlocks the "direct sampling mode", and allows for tuning down to 500 kHz. There is a built in 25 MHz low pass filter for optimizing this mode.Specifications:Packing size: 12*9.5*3.5cmPacking weight: 55gPackage Includes:1* RTL-SDR V3(excluding other accessories)PaymentShippingReturnsContact UsWe accept PayPal via eBay Secure Check-Out .Payment is expected within 7 days of auction close.
