FM amplififier-PCB cost reduction
(OP)
Hello,
I designed a FM "LNA" using a two-layer PCB and worked fined. I was thinking to reduce the cost of the PCB by using a one-layer PCB and removing the ground plane on the bottom layer. I would route the ground connections on the top layer. I have found with PCB manufacturer that cost reduction from two-layer pcb to one-layer is around 27%.
Do you think the amplifier will work without ground plane?

Might be easier places to save pennies.

On a single sided design you will probably end up needing to install a few jumpers. You'll need to take that additional cost into account as it will offset your PCB savings.

Thanks again. I´ll let you know if eventually I manage to do it and save cost.

For high volume, these are not drilled, but are punched. Composite glass/epoxy boards are a common material for low cost in the US. Phenolic are the low cost boards used in Far-East made consumer items. I have seen RF circuits done with 1206 SMT type components as well as axial. Buy several inexpensive TV antenna boosters and take a look.
