TDA8050A QPSK Transmitter

TDA8050A QPSK transmitter,The Quadrature Phase Shift Keying (QPSK) transmitter IC is a monolithic bipolar IC dedicated to quadrature modulation of the I and Q signals. It includes:Two double balanced mixersA balanced voltage controlled Oscillator (VCO) with 0 to 90 degrees signal generation for modulationA Phase locked loop (PLL) for IF frequency controlA conversion mixerA PLL for RF frequency controlA gain controlled output amplifierA 3-wire bus and an output Buffer Two PLLs are incorporated, the first PLL includes:A fixed main dividerA crystal Oscillator and its programmable reference dividerA phase/frequency detector, combined with a fixed Charge Pump The second PLL includes:A divide-by-four preamplifierA 12-bit programmable dividerA crystal Oscillator and its programmable reference dividerA phase/frequency detector, combined with a programmable Charge Pump which drives the tuning Amplifier including 30 V output.
