This project is concerned with creating RF front-end modules, such as PAs, LNAs and filters, that can be used together with an SDR platform in order to create a custom wireless solution.
Dual PA and Tuner
Dual-channel PA module based around Sony wideband (UHF-3800MHz) configurable MMIC power amplifier and Sony 2-Bank (5-bit series cap-array and 4-bit shunt cap-array) tuner devices, with USB configuration via Atmel AVR microcontroller, which also provides external GPIO for e.g. antenna switching or filter insertion via coaxial relays.
