TDA8260
Overview
- Direct conversion Quadrature Phase Shift Keying (QPSK) and 8-Phase Shift Keying (8PSK) demodulation (Zero-IF)
- Frequency range: 950 to 2175 MHz
- High level asymmetrical RF input
- 0 to 50 dB variable gain with AGC control
- Loop-controlled 0 to 90° phase shifter
- High AGC linearity (<1 dB per bit with an 8-bit DAC), AGC voltage variable between 0 and 3 V
- Integrated 5th-order matched baseband filters for in-phase (I) and quadrature (Q) signal paths
- Controlled I-to-Q gain balance
- I2C-bus controlled PLL frequency synthesizer
- Low phase noise
