W7ZOI bi-directional RF amplifier PCB

It’s been a busy month. Sent two PCB designs out to Seeed in China for fabrication. The first one is a reproduction of W7ZOI’s IF amplifier circuit. This circuit is termination insensitive, and bi-directional. One could use two of these amplifiers, on each side of a crystal filter to reuse the it for transmit and receive. W7ZOI designed this as a contribution to the BITX transceiver aficionados. This is my own PCB design. I added SMA connectors and prototype space.
