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.

Example code and description how to use ESP32 low noise amplifier (LNA), including Arduino library and ESP-IDF component

LNA with filter for 400-440 MHz (UHF for amateur satellites)

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.

SDRFunk - Radio Receiver Chrome Extension

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

Designing an ultra low-noise amplifier by python.

CC1190 CC1312R1 Sub-G Ping pong example

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.

Osmocom BTS amplifier (LNA + PA); mirror of https://gitea.osmocom.org/cellular-infrastructure/osmo-bts-amp

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.

This work shows the design of dual band low noise amplifier at 1.1GHz and 2.4GHz using ADS software

SK66112 NRF52 PA/LNA BLE Ping pong example

This is a repository for Proof of Concept of Design and Implementation of a C band Low Noise Amplifier for Geo-Sat Communication

LNA bias values currently need to be entered manually into the SPF SHIELD GUI. These values need to be looked up in as-built documentation, which is an extra step allowing human error. This code extracts the relevant data in a format that SHIELD can autopopulate the LNA bias fields.

Very low noise <0.8dB band pass amplifier to multi frequency bands.
