Overview
INTEGRATED CIRCUITS DATA SHEET TDA8050A QPSK transmitter Product specification File under Integrated Circuits, IC02 1999 Nov 05 Philips Semiconductors Product specification QPSK transmitter FEATURES • Programmable gain • PLL controlled carrier frequency • 3-wire transmission bus • 5 V supply voltage.
APPLICATIONS • QPSK modulation.
GENERAL DESCRIPTION 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 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.
