SHIFTER
Input signal from Lo1 is send to digital
circuit of T-type flip-flop through frequency
doubler. Output signal from T-type F/F is
changed to same frequency as Lo1 input
and that have quadrature phase shift, 0

. These circuits have
function of self phase correction to make
correctly quadrature signals.
BUFFER AMP.
Buffer amplifiers for each phase signals to
send to each mixers.
MIXER
Each signals from buffer amp. are
quadrature modulated with two double-
balanced mixers.
High accurate phase and amplitude inputs
are realized to good performance for
image rejection.
ADDER
Output signals from each mixers are
added with adder and send to final
amplifier.
