Post H-Mode Mixer For Homebrew Radio Projects
As development of my modular Homebrew Multi-mode HF Transceiver continues here is another one of my modules... This is my H-Mode mixer module, my transceiver project will contain two of these used in both the receive and transmit paths. The module shown here has solid state RF switching on the RF port.

Built and working module (PCB size is 75mm by 50mm):


The schematic diagram:


I have built five H-Mode mixers based on the circuit above and all have worked without issue. Currently I lack a dual frequency precision two tone test oscillator to carry out IMD measurements though it is project I will undertake soon!

Hope you find my project and modules of interest, more will follow soon.
