QPSK MODULATOR
FEATURES *Programmable gain *PLL controlled carrier frequency *3-wire transmission bus *5V supply voltage.
Product Overview
APPLICATIONS *QPSK modulation GENERAL DESCRIPTION The Quadrature Phase Shift Keying (QPSK) transmitter IC is a monollthic 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.
