50 MHz Upverter using the TA7358 as Mixer

This upverter is based on the TA7358 FM front-end, which internally provides an RF amplifier, a mixer and a local oscillator. As the local oscillator, this project uses a module with a fixed frequency of 50 MHz.

Schematic of the HF to VHF upverter with the TA7358

The supply is 5 V, taken directly from the USB port or from some other source.

Etched board next to the reference project

Printed layout and board painted for etching

Board with the first components soldered

Finished board, with the inductors and SMA connectors

Board installed in the tin, with the frequency markings

Open tin, with shielding between the stages

Closed Barkleys tin, with the SMA connectors

For the enclosure, a Barkleys candy tin was used, providing excellent shielding and a nice finish.
