This step in the development and prototyping of the Amateur Radio Satellite Transceiver project contains:
- 150 MSPS differential current steering DAC with dynamic element matching
- 8 GHz differential Colpitts topology VCO
- Baseband to IF mixer
- High-speed buffer amplifier
- RF IO driver which can be combined with an off-chip distributed balun to drive off chip loads
The combination of the above items forms a digital input, 8 GHz RF output transmitter prototype. Note that there is no filtering included at this point, therefore this cannot be seen as a complete transmitter. It is an experimental evaulation of the building blocks.
This is a shuttle prototype run of the larger project which can be found here: github.com/yrrapt/amsat_txrx_ic
