The incoming signal from the antenna via the PIN switch passes through a high pass fil-
ter to the RF amplifier, Q101. The 50Ω output from the amplifier is coupled to a varicap
tuned triplet which provides the spurious response rejection necessary for the first
mixer. An attenuator is provided at the output to allow for fine adjustment of the front
end gain.
