BLOCK FUNCTION/OPERATION BLOCK DIAGRAM
90YPHASE SHIFTER Input signal from LO is send to digital circuit of T-type flip-flop through frequency doubler. Output signal from T-type F/F is from LOin
changed to same frequency as LO input x2
and that have quadrature phase shift, 0I 90'C 1801 270Y These circuits have
function of self phase correction to make correctly quadrature signals. 2 F/F
BUFFER AMP. Buffer amplifiers for each phase signals to
send to each mixers. M j j
MIXER Each signals from buffer amp. are
quadrature modulated with two double- ×
balanced mixers. K y
High accurate phase and amplitude inputs
are realized to good performance for image ]×1
rejection. u<y
ADDER Output signals from each mixers are added with adder and send to final amplifier. to MODout

In real-time instruction trace, four status lines provide information on processor activity in real time (PST pins). A four-bit wide debug data bus (DDATA) displays operand data and change-of-flow addresses, which helps track the machine's dynamic execution path.
