8 UPC84GR MODULATOR NTERNAL FUNCTONS Block Function/Operation Block Diagram from LOin 9 Phase Shifter Buffer Amplifier Mixer Adder TEST CRCUT Desired Matching Network mpedance, Based On Load Pull Measurements nput signal from LO is sent to a T-type flip-flop through a frequency doubler. The output signal from the T-type F/F is changed to the same frequency as LO with a quadrature phase shift of, 9, 8, or 7. These circuits provide self phase correction for proper quadrature signals. Buffer amplifiers for each phase signal are sent to each mixer. Each signal from the buffer amps is quadrature modulated with two doublebalanced mixers. High accurate phase and amplitude inputs are realized to provide excellent image rejection. Output signal from each mixer is added and sent through a final amplifier stage to pin 6 for further off-chip filtering if necessary. flo = to 4 MHz PN = - dbm / SGNAL GENERATOR.8 pf 8. nh Frequency ΓLoad (Mag) ΓLoad (Ang) 9 MHz MHz MHz LO N (OPEN) LO N L 9 RF OUT For 9 MHz match L = nh or Microstripline equivalent VCC VENABLE MOD OUT 6 UP CON N UP CON N 4 VCC LO N LO N.7 ~.
