I'd presume Farhan reads here form time to time.
The base design could with mods.
It needs an RF amp(LNA) for RX as on 2M SSB work weak signals are the rule.
This means getting the RX noise figure down and using monoband filters.? This
is more a matter of picking the right devices and board layout plus switching?
that amp out of the way for TX.
The TX power chain line up would have to be radically different.? Between MMIC
devices and the absolute need for decent filtering the low level (ato about 10 to
50mW) part is fairly straight forward.? Once there two more stages should do it
using LDMOS devices (RF06VHF and RD15VHF) using stipline broad band
layout.? This is one case where getting the layout right or even going multi-layer
board can make it an less an iterative process.? ?A larger board can make it easier.
The si5351? goes high enough for VHF work.
VHF is pickier of things like tuned circuit design and also layout is everything.
There is a need for a good monoband 2M SSB/CW radio not only for QRP ops but also for use as 2M IF behind higher frequency transverters.
