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. 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.
