This project is about creation of affordable and easy-to-manufacture prototypes of PCBs which are used to expand the capabilities of existing low-cost SDR receivers based on RTL2832U chip.
This project shows the design process of the main blocks of a typical RX frontend system.
This project is about building a high FOM 2.4 GHz LNA for Bluetooth Low-Energy (BLE) Standards, using 45nm CMOS technology.
Expansion board for Raspberry Pi 4 Model B that eliminates the need for a direct wired connection of radio equipment to GPIO when working with rpitx or rpitx-ui packages. Now, you can use coaxial SMA output, switchable filters, and built-in LNA on one board!
This is a 2.4 GHz LNA project being done for practice using Keysight ADS. This project attempts to automate the design process using python to make it easier.
Complete 2.4 GHz RF receiver front-end designed in Cadence Virtuoso (180 nm CMOS) — cascode LNA, Gilbert cell mixer, and Gm-C IF filter. Serving as the analog verification layer for a 64 subcarrier OFDM PHY baseband. Simulated in Spectre RF.
Singled ended to differential (BALUN) amplifier for direct sampling with RTL-SDR dongle
Open Hardware Low-cost RF probe for power-analysis side-channel attacks (DPA/CPA). Capture power traces from a chip on a standard oscilloscope, no ChipWhisperer required.
Analysis and simulation of an RF front-end chain (LNA, mixer, LO) using MWOffice and VSS. The project evaluates key performance metrics including gain, noise figure, linearity, EVM, phase noise, and image interference.
A full-custom 2.1–2.7 GHz Direct-Conversion (Zero-IF) Receiver Front-End designed in TSMC 65nm CMOS. This repository details the schematic design and SpectreRF verification of a PVT-invariant cascode LNA, a highly linear 50% duty-cycle passive mixer, and a 3-stage Active-RC TIA stabilized via Zero-Nulling Miller compensation.
This is a repository for Proof of Concept of Design and Implementation of a C band Low Noise Amplifier for Geo-Sat Communication
Very low noise <0.8dB band pass amplifier to multi frequency bands.
