ERASynth Micro

A USB-powered signal generator that can generate RF frequencies from 12.5 MHz to 6.4 GHz

This project is coming soon. Sign up to receive updates and be notified when this project launches.


ERASynth provides a clean RF output that can be used as a:

  • Stimulus source for RF testing
  • LO source for down-conversion or up-conversion
  • Clock source for data converters
  • Test signal source for software defined radio (SDR)

Features

  • Frequency Range: 12.5 MHz to 6.4 GHz
  • Amplitude Range: -30 to +15 dBm
  • Phase Noise: -115 dBc/Hz @ 1 GHz output and 10 kHz offset
  • Frequency Switching Time: 1 ms typical
  • Reference: Ultra-low noise 50 MHz VCXO locked to a ±500 ppb TCXO
  • MCU: ATMEGA32U4-MU (same as in the Arduino Micro)
  • Interfaces:
    • Micro-USB for power input and serial access
    • REF In (SMA) for external reference input
    • RF Out (SMA)
    • Pin headers for trigger, external modulation and microphone inputs
    • Pin headers for GPIO, SPI and UART
    • Pin headers for Touch Display Module (3.2” Nextion NX4024T032)
  • Size: 48 mm x 109 mm x 27 mm (including the LCD screen)
  • Weight: < 200 g (including the LCD screen)
  • Power Input: 5 V
  • Power Consumption: < 2.5 W
  • Open Source: Schematics, embedded Arduino code, PC GUI source code, and RS-232 command set, LCD screen source code
