6 GHz RF Signal Generator

PN: PWRMOD-001, Last updated: May 2023 (Rev A)

6.3 GHz Power Amplifier Module

This module generates a 6.3 GHz signal from a local oscillator and outputs over an SMA connector. The device includes a compact, low-noise regulator for generating the main bus voltage and a dual-rail regulator for generating the amplifier gate voltages. The amplifier on the device is listed with a maximum frequency of 6 GHz, but the response curves in the datasheet indicate the component can work up to approximately 8 GHz. Consider adding one additional header on the VTUNE net for the VCO so that the generated frequency can be manually adjusted if needed.

Major components include:
  • HMC637ALP5E
  • HMC358MS8GE
  • LM27762DSSR
  • TPS562201DDCR

3.3V Output Flyback Converter Module

PN: FLBACK-001, Last updated: February 2024 (Rev B)

3.3V Output Flyback Converter Module

This module converts 120 VAC RMS at 60-400 Hz to 3.3 V DC output. The module uses a custom transformer and the UCC28881 for switching. The flyback converter operates in voltage-control mode.

Major components include:
  • UCC28881
  • Custom transformer

Dual ADC Module

PN: ADCEX-001, Last updated: December 2022 (Rev A)

Image

This ADC module includes a rad-hard power regulator from Intersil and two ADCs: 1 isolated ADC and 1 non-isolated ADC. Input signals for the ADC and isolated +5V power are provided through 3 SMA connectors. An I/O pin header is included for access input/output data and programming the non-isolated ADC.

Major components include:
  • ISL75051ASEHVFE
  • ADC128S102CIMTX
  • AMC1203BPSA
Link

USB to UART Bridge

PN: USBUART-001, Last updated: January 2023 (Rev A)

Image

This module provides USB-to-UART conversion in a small form factor. The device includes additional ESD protection on the input and output sides of the device for added reliability. Additional protection could be implemented with an enclosure and a chassis guard ring applied to the board edge.

Major components include:
  • CP2102
Link

USB to UART via RJ-45 Module

PN: USBUART-001, Last updated: April 2023 (Rev A)

Image

This module provides USB-to-UART conversion over a shielded Ethernet connector for interfacing with networking equipment. This small form factor device is an alternative to older RS-232. The device includes additional ESD protection on the input and output sides of the device for added reliability. An enclosure and a chassis guard ring on the PCB could be used for additional ESD protection.

Major components include:
  • CP2102
  • SN75C3221PWR
Link

LED Shield for Arduino Uno

PN: LEDSHL-001, Last updated: June 2023 (Rev A)

Image

This shield board for an Arduino Uno was originally created for the Altium Education program. This board includes a 12V to 5V regulator circuit and two CREE LEDs. It has been modified from its original version to include a 2-pin header for power input.

Major components include:
  • TPS562201DDCR
  • MKRAWT-00-0000-0D0HG235H
Link

USB Charger Module

PN: USBCHG-001, Last updated: January 2023 (Rev A)

Image

This 2-port USB charger module operates at 12 V input with maximum power output of 15 W at 5 V (3 A maximum current) per port. This device uses edge connections for a pluggable interface, although it could be modified to include a through-hole connection to a pin interface or flying leads.

Major components include:
  • LM73606
  • TPS2549
