Product specification
QPSK transmitter
TDA8050A
FEATURES
Programmable gain
PLL controlled carrier frequency
3-wire transmission bus
5 V supply voltage.
APPLICATIONS
QPSK modulation.
GENERAL DESCRIPTION
TheQuadraturePhaseShiftKeying(QPSK)transmitter IC
is a monolithic bipolar IC dedicated to quadrature
modulation of the I and Q signals. It includes:
Two double balanced mixers
A balanced voltage controlled oscillator (VCO) with
0 to 90 degrees signal generation for modulation
A phase locked loop (PLL) for IF frequency control
A conversion mixer
A PLL for RF frequency control
A gain controlled output amplifier
A 3-wire bus and an output buffer.
Two PLLs are incorporated, the first PLL includes:
A fixed main divider
A crystal oscillator and its programmable reference
divider
A phase/frequency detector, combined with a fixed
charge pump.
The second PLL includes:
A divide-by-four preamplifier
A 12-bit programmable divider
A crystal oscillator and its programmable reference
divider
A phase/frequency detector, combined with a
programmable charge pump which drives the tuning
amplifier, including 30 V output.
