Software Defined Radio Transmitter
Description
Hardware to transmit anything on any frequency. That means any information / modulation can be transmited on a channel between 750 and 1150 Mhz, which is the possible internal PLL frequency-range for ADRF6701. The I/Q signals are feed through a VGA-compatible 15pole-DSUB connector.
This board is intended to be used with VGAtoBaseband.
This is a prototype with a teensy controlling the ADRF6701. The frequency can be adjusted using a USB terminal connection.
The board has a 50Ohms SMA connector transmitting about 0dBm using VGA signals (0.7Vpp).

TODOs
- use ADRF6755
- shrink board size
- don't use eeprom 24C02
- don't use teensy, maybe Attiny
- don't use sot-123 diodes
- rf power amplifier
- use a display to show the current freq.
- rotary switch
